Greetings,
I am trying to figure out how to calculate p, q, and M using cumulative and noncumulative sales data. I don't think a regular regression would work because of the shape of the data (S curve)- linear regression would not be an accurate predictor. Has anyone ever done anything like this in Excel (or SPSS) and could offer some suggestions or a template?
Thanks so much!

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.

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!

A previous poster explained what I also need; there were no responses,
so I thought I would try again.
Does anyone know of an Excel template--or a small stand-alone
program--that will calculate the interest/principal breakdown when
payments are varied in amount and frequency? Free or low-cost, please.
I need one that will work on my Mac/Office 2004. I will need to print
out periodic reports.
Here is the way the previous poster described it:
"Excel template: Loan Amortization for random/irregular payments,
figures days
between payment dates.
I have a loan with a variable beginning balance and irregular payments
with
annual large payment. (based on collections)
Would like to enter payment and date.
then Excel would figure days since last payment, interest amount,
principal
amount, Ending Principal balance.
And total interest paid, total pricipal paid
If I change the starting principal, excel would recalculate all
entries."
Thanks very much.

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.

I have a set of data about with approx 7500 cells all contained in one column. The data has a series of peaks that happen, and I need to identify each peak value and place it in a cell. The peak does not occur at regular intervals but they are somewhat regular, as in within 130-230 data points. So, if one could find the first peak in the first 200 cells, identify it and store it somewhere, then look in the next 200, store it, etc. I don't know how to do that in excel. Please help
Thanks

Does anyone know of a non-commercial roster template that would suit 7 day/24 hour/4 person shifts?
Currently we use a totally manual spreadsheet which looks like a Rubik's Cube and does not offer any form of automation in order to speed up entry adn ensure no doubling-up or missing shifts.

I have a spreadsheet with data from A1 to H1 down to A275 to H275. I select all of it, Copy, go into the Sheet2 tab and select A1, Paste Special -> Transpose and it give me the following error message:
Quote:
The information cannot be pasted because the Copy area and the paste area are not the same size and shape. Try one of the following:
- Click a single cell, and then paste.
- Select a rectangle that's the same size and shape, and then paste.
For the life of me, I can't figure out why it's not working! I have done this many times with other spreadsheets. Has anyone ever experienced this? If so, were you able to resolve it and how?
Many Thanks,
Mike

Hello,
Please help!!!
We have a client who will pay using the 1/4, 1/2/ and 3/4 of an hour increments as follows:
From the hour mark to 6 minutes = 0 time paid
Over 7 minutes to 15 minutes = 1/4 hour 15
16 minutes to 30 minutes = 1/2 hour 30
30 minutes to 45 minutes = 3/4 hour 45
46 minutes to 60 minutes = one hour.
They work on shifts and the operation is 24 hours. Each gets 30 minutes for breaks which is not paid. Pay is biweekly and overtime is anything over 40 hours. Currently, the template we are using looks like this (sorry, I could not figure out how to paste it so you can see it in Excel layout):
WEEK 1 Sunday Monday Tuesday Wednesday Thursday Friday Saturday
5/16 5/17 5/18 5/19 5/20 5/21 5/22

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.

Sale = A1
Cost = B1
Margin = C1
I know to calculate Margin its' C1=1-(B1/A1) and to calculate Sale its, A1=B1/(1-C1), and I can do that in separate columns. But...... I'm tasked with trying to find a way so that I can do it in three columns. As in if I change cost then margin recalculates or if I change margin then sale recalculates. I'm thinking that this is going to cause a circular error but my boss says there's got to be a way to do it, figure it out. Any suggestions?

All on a sudden my mouse pointer in excel is not working properly. I cannot use my mouse to drag and fill, or to adjust the page break lines in the Page Break View mode. It always is in the shape of the white cross with black border and never changes it shape when pointed at the lower right edge of cells too. Now.......what to do in order to get out of this problem.

I have an excel form, I want my users to be able to open the form, fill in appropriate data, then click the save button. When the button is clicked, the data in the form should be saved to a new file and then the original form should be reset (clear all values) for a new set of data entry. When the data is saved, I want the new excel sheet to be saved to a location specified within the macro so the user doesn't have any options and I want the title of the new file to be the value of one of the cells.
I'm new to macros and would appreciate any help this board can offer. Thanks...

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

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 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

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?

Hello -
I am using Excel 2007. In prior versions of excel, when copying data, if I wanted to copy visible cells only, I would select "Go To, Special, Visible Cells Only" and then copy a range a cells. The default was always set to copy everything (including hidden cells), unless I specifically selected copy visible cells only.
In 2007, the default is somehow set to always copy only visible cells. Sometimes, I want to be able to copy all cells including those hidden but cannot seem to figure out how to swith this default option. I looked under Excel Options and did not see an option there.
I don't want to have to unhide and rehide everything each time i copy. I know i could do the hiding and unhiding via VBA but would prefer not to have to.
Thanks for your suggestions.
