Data Analysis Add In - Storing Multiple Regression Coefficients - Excel |
|
Hi Guys,
I am doing some statistical work with Excel 2007 and have been using the data analysis add-in to do some regression. In terms of a standard linear regression, one can enter the =slope(known y's , known x's) formula to find the regression coefficient for x. My regression is slightly more complicated as it has multiple independent variables (i.e. the y variable is not just a function of x, but also of another variable, say z). I can perform a multiple regression easily but I would like to be able to store the coefficients of the multiple regression as I must eventually add the coefficient estimate for x and z together. The multiple regression output is in a standard format however as I have to repeat this process for 1500 firms (one regression for each) it would be much more convenient if excel just reported the two coefficients for each regression. That way I could copy a formula across all firms and not use the standard regression window 1500 times.
Is there anyway I can perform the multiple regression formulaically, outputting just the two coefficients I require from each regression?
I apologise for the long winded post. Any help is very much appreciated. Thanks in advance.

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.

Hello, I'm trying to count the number of times a name appears across multiple worksheets but I can't seem to figure it out.
I have 6 sheets to count and all the names are in column A (from A1:A100) on each sheet. The names are not in a particular order.
On sheet 7 I want to have a cell beside each persons name that counts the number of times their name appeared on the other 6 sheets.
For example Sheet 7 (called total) would have
Joe 5 (where 5 is the outcome of the formula I'm looking for to count all the times "Joe" appears on sheets 1-6).
I have it counting per sheet with =COUNTIF(A1:A130,"name") but this is not quite what I am looking for.
Thanks in advance for any advice.

I have a textbox in my userform where anything typed in the box is entered into cell A2 in my worksheet. However, multiple lines of text are not properly displayed in my worksheet. I have enabled MultiLine and EnterKeyBehaviour in the properties window of the textbox so I can type multiple lines in my textbox. The problem is that when I press the button to enter the text from my txtbox to cell A2, the cell doesn't actually display the text in separate lines. It just places a square symbol in the place that enter should have been pressed and the text should have been split into separate lines.
How can I get the separate lines of text in my textbox to be properly displayed in a cell? Thanks for your help in advance..

I am trying to sum all numbers <0 using the SUMIF formula in Excel 2003.
FORMULA: =sumif(range,criteria,sum_range)
I got it to work, but I have cell ranges to total that are not next to each
other (such as A5:A15 and C5:C15).
When selecting the ranges for the formula, Excel writes them A5:A15,C5:C15
because of the comma (,) between the cell ranges Excel is reading the A5:A15
as the range and C5:C15 as the critera. How can I get this formula to allow
me to select multiple cell ranges?
All help is appreciated.
Thank you.

Good afternoon,
Is there a way to enter a colon into a standard number to create a value that can be formatted into a 24 hour time value ?
eg a time is listed as 1345 with a general number format, and I want it returned as 13:45 witha custom format of hh:mm.
Other than creating a table and using a vlookup function, I am hoping there is a better way?

I know I can put a $ sign for all references in a formula for a cell by pressing F4, but is there a quick way for doing this for multiple cells (e.g. a column) or do I have to go through all the cells individually?
e.g.
=A1
=A2
=A3
to
=$A$1
=$A$2
=$A$3
Thanks
e.g.
=A1
=A2

Is it possible to set multiple validation for a single cell in excel? Its
pretty straight forward to set a single validation so that a message is
displayed when incorrect data is entered. However, adding another validation
seems to delete the old one. Thanks in advance.

I have an excel 2007 file sitting in a shared network folder. I only want one user to be able to make changes at a time (any other users would get a read-only). For some reason it currently does not do this, and I have multiple users with the same doc open. I'm concerned that changes will get over-written when 2 people are saving their changes. Can anyone help me with the settings for this.
I have a merged cell which contains a text with multiple lines.
I want to split the lines into multiple rows.Each line should come in a different row.
I want to do this using macro.Is there is anyway to do this?
There is an option to split the cell into multiple cells on the basis of the delimiter, but there is no option to split them into rows.

Hi, can anyone help me with the below...
Im looking for a vlookup formula which will give me the maximum number from a list which contains multiple matches, i.e.
Lookup number 1 from column A, then give me the largest number from column B
example table:
A B
-----
1 5
2 2
1 11
3 2
4 5
the result would be 11
thanks all!

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

Is it possible to import a single text file into Excel, splitting the incoming data across multiple worksheets rather than a single worksheet? Each each row on the text file would be evaluated by the value in one of it's "columns" and written to the appropriate worksheet. The file is "!" delimited and has 11 columns for each row.
Currently, I import the file into one worksheet and cut/paste the rows manually into new worksheets/tabs. The files are very large, sometimes exceeding the 65,536 row limit, which I could avoid if the data was split out coming in.
Any help anyone could provide would be WONDERFUL. Thanks!

Is it possible to apply a filter to multiple sheets within the same Excel workbook, using the same filter criteria?
For example, suppose you have tables of data on 3 different tabs, all having the same headings. Suppose one of the headings is "gender". If you apply a filter to the table on Sheet 1, to only show the rows containing the word "female", is it possible to have the tables on Sheets 2 and 3 automatically update to only show the "female" rows? Or would you have to manually update the filter criteria in Sheets 2 and 3?
I hope this makes sense. Thank you in advance for any help.

I'm trying to come up with a solution to calculate the man hours and days worked over multiple sheets.
I have a file that has 8 sheets. the first seven sheets are the days of the week and the 8th sheet is where I want to calculate the hours.
The days of the week consists of "Name" "Date" Hours"
The 8th sheet consists of "Name", "Days of the week in their own column (7 columns in total)", "Total Hours" and "Total Days Worked"
Now... each day is always a different group and what I'm hoping for is to create a formula that can grab each name with their hours and throw them into the 8th sheet. So when the end of the week is done I have all the Employees weekly hours and days worked all finished.
I hope this makes sense. This file is to track about 100 employees that are on a rotational work schedule.
I have attached a sample file.

Hello,
I'm pretty new at VBA and was wondering if you could help me out on this:
I have created a VBA userform but will need to have it used by at least 5 users. My question is, can it be done with all users working at the same time and when saving their work all data entered will go to one master excel sheet? if yes, would you be kind enough to share the code?
MS Access is not an option for me so I was wondering if you could help me do this in excel.
thank you so much and would really appreciate to hear from anyone soon.

I'm sure this has been addressed before, and I'm sure one of you 50lb heads has the answer I'm looking for. I want to generate a bank of 200-300 questions in excel and be able to make a test of 50 questions that will be different every time. I want to be able to do this with multiple choice questions as well as just plain essay questions. Can I have some instruction or examples? Thanks guys!
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

Hello ,
Here is my issue:
I have a list of SKUs in Excel and I need to add one same word to 500 cells that have pre-existing text in the cells. See example below:
1) List of SKU's in cells:
34
35
39
55
2) text that needs to be added IN FRONT of every number:
DF
So the result would be:
DF34
DF35
DF39
etc.
How do I do that in a formula and not manually? I found another similar thread and I understand how to do it from the instructions there but the same text goes on the back and the result is: 34DF but I need it to be like: DF34.
I am using Office 2007 for mac.
Thank you for the help,
Chris
