Weibull Paper In Excel - How?

Hi,

I want to create Weibull paper in Excel. The problem is the labelling
at the Y-axis.

I want to label probabilities (between 0.1 and 99.9%), but want to plot
the transformed logaritmic data; calculated out of the probability via
ln(ln(1/(1-p)))

X P (probabiliy, label) Y (transformed data; to
be plotted)
155 97,89% 1,350040182
325 97,61% 1,317875745
500 97,34% 1,288316244
525 97,07% 1,26088904


How can I do this either with or without VBA?

Has minitab this functionality included? Does it calculate beta and
eta?

thanks for the help,
Roger

Hi there. I know it sound like a really simple thing but its really stumped me.

Instead of the y axis being on the left hand side, i wish for it to cut at 0,0. I have positive and negative values and I need it to be in the centre instead of on the left.

I have tried formatting both the axis and it would appear that the x axis already cuts the y axis in the right posistion so i need to format the x axis to make the y axis cut it at 0,0. I have already tried typing in 0 instead of 1 and it keeps saying it need to be number more than or equal to 1.

Any help would be greatly appreciated.

How can I stretch a spreadsheet to fit the page? If I try to make it one page by one page, it changes nothing. If I change the percentage, it becomes two wide...I am just trying to change the height so that it can be read on an 8.5 x 11 piece of paper.


This may be less of an Excel question than a general data display question, but I'll try here.

I have 3 variables that I'm charting. I have one on the primary axis and it's values are in the billions. I have one on the secondary axis and it's a percentage. I need to display a 3rd who's value is in the millions. If I put it on the primary axis, you cannot see modest changes.

Is there a tricky way to get all three on one graph? I know I could split on two graphs, so that's my backup plan.

Thanks,

Dave


Hi there

I am trying to calculate our On Time Delivery. I want this as a simple percentage of jobs. I have got this running in the following way:

Column M - Estimated Delivery dates
Column N - Actual Delivery dates
Column O - =IF(SUM(M2-N2)>0,1,0)

Then I have calculated On Time Delivery as: =SUM((SUM(O2:O252))/(COUNTA(N2:N252)))

This seems to work fine. My problem is, if we enter a date in Estimated without a corresponding Actual date, the formula for Column O fills out anyway and improves our On Time Delivery Percentage. How can I set this up so that the formula doesn't calculate if there is no data in Column N?

Any help much appreciated

Thanks,

James


I want to add data points to the scatter plot that are not part of the data
ie. add points to find their concentration on a standard curve.



Hi,

Im working with a large data spreadsheet that has Yes and No answers in different columns. There are blanks within the selection too.
I need to calculate only the Yes.
I have tried using the filters in the Pivot Table field list and they are not working.
So now i'm trying to add a COUNTIF formula in the Calculated Fields section.
The formula I'm using is =Countif('Time limit extension'="yes") and i get the answer "too few."
What should I be using in the formula to get the calculated field to work? I have search the whole forum and I haven't found an answer that can help me.

Please HELP!!!


I have an excel worksheet that adds two other worksheets in a data
triangle. I copied it to create a new data set and used find &
replace to change the worksheet references to the new ones.

The cells still contain the result of the old formula referring to the
previous worksheets. The only way I can get the formula to return the
correct result is to edit (F2) each cell and press enter. Calc now
(F9) does nothing.

I've seen this before, but this time, I need to calculate many
thousands of cells and don't have time for this workaround.

Any ideas?

Thanks.

So I've got some data, which has the approximate form of a sine function. I want to find all the x-axis intercepts. I tried using the intercept function and swapping around the y values for the x values, but it only returns 1 value (so I'd guess it uses a linear regression to estimate a single line through the axis).

I was thinking of trying a nested if/and statement but I haven't quite figured out how to do it. Basically I want to identify the two values where it switches from positive to negative and also indentify the values where it goes negative to positive, I can then fit a straight line between them to find a better approximation of the intercept (though it might not be necessary). Preferably I'd like it all one function as I'm not doing it in VBA (I might do later though, we'll see).

Can anyone suggest how I'd find these value or the x-intercept. Any help would be greatly appreciated.


how can i find the coordinatres of the maximum point on a curve plotted in

Hey everyone,

I'm really hoping someone can help me with this...

I need to plot percentages over time in a line graph in excel. I don't want to have to do a percentage equation in the spreadsheet, I just want excel to take two sets of values and display the percentage in the chart. For example, I need B1 as a percentage of B2 for week 1, C1 as a percentage of C2 for week 2, etc....
Can someone please offer a suggestion for how to do this? I would really appreciate it.
Also, would it be possible to link data from other sheets in the workbook into one single chart?


I have a file that became too big due to phantom bloat, unused range saved by Excel and all that kind of reasons. Thank to previous posts on that board tackling that issue, I was able to find how to proceed to reduce the file back to its normal size.
But I did so in a beta file (test file). The real file has become so big (103MB!) that Excel cannot even open it anymore! The file contains archive info that we do not have anywhere else.
Is there anyway then to open the file or to reduce its size without opening it (through magics...)? I just honestly don't know how to retrieve that info before deleting that file.

Thank you very much for your help.


Hello,

I have two columns of data: column A contains the date and time in the form dd/mm/yyyy. Column B contains a number value. All the times are in order, so column A looks like:

01/01/2007
02/01/2007
03/01/2007

I have data from 2007 to 2010. I need to calculate an average daily value (in column B) for each month, and display it in column C. So, for January, I need to calculate the average of 31 days, February, 28 days, etc.

Is there a function I can use to do this? I've been trying the AVERAGEIF formula but can't get it to work. Any ideas would be much appreciated!

Many thanks,
Caitlin


How would I create a system where an excel file is updated in real time with new values? I have a program which logs data, and I want to have excel open, plotting the data in real time. Is this possible?


I have a excel spreedsheet that contain external data. I would like to put a
button in the excel sheet to update the sheet without doing right click and
refresh.
My user here are very dummies.



Okay, so I tried (for hours) to find a solution to this and have finally gotten frustrated to the point where i think asking here will be my best bet.


Basically I want to export data from excel worksheets to various places on a word document I had. I have created a word template as well as bookmarks for that template, as that seems to be the recommendation for performing such a task with excel.

My problem is ... Now what?

I basically have 1 constant worksheet that contains all my affiliates info (Name, Address etc), which i'd like to use to populate some bookmarks in my word template, and then i have another worksheet for the previous month, indicating sales etc for that affiliate. I intend on adding a new worksheet every month that i would use to create new invoices.

Furthermore, i'd really like to be able to update a new file (or perhaps a new page on the same file) for each company with the use of a button, similar to the one's you'd see in an access form.

Can anyone help? Let me know if you need me to clarify.

Thanks!

I need information on how to enter the proper syntax (formula) so that excel
can calculate overtime hours. In california over 8 hrs in one day is
overtime. The 8 would be considered regular hours and anything over is OT.



Is there a way to use the new conditional formats (data bars, icon sets, etc) in PowerPoint? Basically, I'd like to create a table that shows icons based on data, like in Excel? I know I could paste a pre-made Excel table as a picture, but I'd like to avoid that if possible.

Thanks!


I need a formula to calculate Turn Around Time. Find below the sample data and details for your reference.

Received Date & Time: 10/29/2010 3:27:00 PM
Completed Date & Time: 11/1/2010 3:57:32 AM
Business Hours: 08:00 AM to 05:00 PM
Non Business hours: 05:00 PM to 08:00 AM
Weekdays : Monday to Friday
Weekends: Saturday & Sunday

If I calculate TAT for this time period it should show me 1 hour 33 minutes, why because business hours are closing by 5:00 PM on 10/29 so it should not calculate duration after 5:00 PM to until 08:00 AM on next day, however 10/29 is Friday so formula should calculate the duration from 10/29 Friday 3:37 PM to 10/29 5:00 PM and again it should calculate from 8:00 AM on 11/01 Monday and formula should skip Saturday & Sunday.

In this scenario I have completed the task before 8:00 AM on 11/01 so it should show duration of 1hour 33 minutes.

Please let me know if you need any more details


Is there an Excel guru that can help with this - its related to "drop down menus"


I have 2 colombs of data.

AT the bottom of the first, I have created a drop down menu using the "data validation" feature in excel.

At the bottom of the second colomb, I have used an "IF" function that returns a result, which depends on what value is chosen from the drop down menu in colomb 1

The problem I have is that I want the TRUE result from the IF function to be another drop down menu, being the data in colomb 2.


How do you write an IF function where the TRUE result is a drop down menu??
I tried to create a drop down menu of colomb2 elsewhere in the spread sheet, and used that cells location as the TRUE value, but this didn't work either...

ANy suggestions??


Hi All,

If I drag a formula to the right it adapts the column letter in the formula from A to column B, which is standard Excel functionality.

However, if I drag the formula to the right I want Excel to skip a column each time.

In other words:

=A1 ; = B1 ; = C1

Should be

=A1 ; = C1 ; = E1 etc...

Is there an easy trick to do this?

Thanks,

Michiel


On my calculator, if I divide 462,534.05 by 335 I get 1,380.70. Then if I times 1,380.70 by 335 I get 462,534.50. Which is what I need it to be because I need to calculate the difference of a figure not dividing equally.

On excel, if I divide 462,534.05 by 335 I get 1,380.70. Then if I times 1,380.70 by 335 I get the SAME result of 462,534.05.

I have to account for the difference of not dividing equally so there is some format or accounting function that's preset that I don't want but I have no idea how to fix it or format my excel sheet to calculate as my calculator would.

Please can someone help? Thanks!


I am trying to do a very simple copy and paste of a simple formula in Excel 2007 and nothing seems to be working. Excel will not let me copy and paste a formula and will only paste the value into to workbook. For instance, if I make a very simple spreadsheet such as:
A1 type in 10, A2 type in =A1 (calculated A2 to be 10)
B1 type in 5

And then click the copy on B1, and then click paste special on cell B2, the only options it gives me are text and unicode text and so no matter how I paste, cell b2 will always be populated with a value of 5. I cannot imagine a simpler copy and paste and no matter what I do I can't make this work.
All cells are formatted as general. It seems that all copy and pasting of formulas in my excel has been disabled. If I open any spreadsheet on my computer, I can't copy and paste formulas, but do the exact same thing on the exact same spreadsheet on any other computer and it works no problem.

Any help?


I have a spreadsheet where I need to calculate the increase in % one year over the other in column D for Eg if Profits are 95415 in Jan 2008 (Column B) and 80215 in Jan 2008 (Column C), then the % Increase will be (95415-80215)/80215 *100

I can calculate the formula for this, but the problem comes where for eg there is a loss in Jan 2008 for -95415 and there was a profit in Jan 2007 for 80215. How do I set up formula to take negatives & positives into account in calculating the increase or decrease/

Your assistance or anybody's on the forum will be greatly appreciated

I would like to copy a small table from Word into one cell in an Excel
worksheet. The first column of the table is a list of numbers. I tried
converting the table into text with manual line breaks and tab stops to
divide columns and rows, but that didn't solve my problem.

Excel pastes the data into several rows. When I try to merge them, I
get a warning that the selection contains multiple data values, and
merging into one cell keeps the upper-left most data only.

What I tried that didn't work:
* Formatting the Excel cells as text before pasting the data.
* The various options for "Paste Special." The closest I got was
inserting the table as a Document Object, which could be a workaround,
I guess.
What I am saving for when all else fails:
* The obvious solution of copying row by row into one Excel cell.

The data in the table is information about my dad's medications. I
would like to have reference charts of how to identify the strength of
each tablet by its color and markings. I got the info from the
manufacturers' websites and entered it into tables in Word, which I
would like to copy into a more comprehensive file I am creating in
Excel. The first column of each table is the strength of the tablet,
entered as 1 mg., 2 mg., etc. The subsequent columns describe the
shape, color, and markings. There are 3 tables, each with about 4-5
rows.

Is there a way to copy each one - whether as a table or as text - into
a single Excel cell without losing data?

Many thanks.




I am trying to figure out how to write a formula to figure out production cycle time.
We will be building 8 "widgets" a day.
We will work 10 hours a day.
There is a 20 minute break at 9:20 am.
Production shuts down for lunch 30 minutes for lunch at 12:30.
Production starts at 6:00 am.
Here is what I can do.
Production cycle time = (10*60)-30/8 or 71.25 minutes
If we start at 6:00 am, the first scheduled cycle completion time = TIME(6,0,0+71.25/1440)

My problem is when I am trying to use a logical "IF' statement to account for the 20 minute break or lunch and still calculate the end of each cycle time through the day I receive a number of error messages.
This is the formula I am trying to make work. I have the cell the formula is in, formatted with a "mm,ss" format.
=(IF(D4+G1/1440>9:20,(D4+G1)/24,(D4+G1+15)/1440))
I have included an attachment to help (a picture is worth a thousand words).

Any help will be greatly appreciated.
I have bought a number of books in an attempt to figure this out, and I am still stumped
