Multivariate Polynomial Regression In Excel

Hi All,

I am trying to do multivariate polynomial regression in excel, trying to correlate data of the form y=f(x1,x2) with second order polynomials:
Y = c + a1*x1 + a2*x1^2 + a3^x1^3 + b1*x2 + b2*x2^2 + b3*x2^3

Using the following command, I have achieved this:
=LINEST(A2:A10,B2:B10^{1,2,3,0,0,0}*C2:C10^{0,0,0, 1,2,3},TRUE,TRUE)

Can anybody tell me the theory Excel uses for this kind of regression?

Thank you very much 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.


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??


Could you guide me please....

I need to insert 5 blank rows repeatedly between every existing data rows
for approximately 300 rows.

If I go about doing the repeat short-cut "Control+Y", it just repeats
inserting ONE row only between the consecutive data row.

Is there some command, which helps me highlight all the rows & allows me to
insert 5 blank rows between every consecutive existing data row?

Thanks in advance for your kind advice.



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...


Dear Sirs,

Am in need for this solution very badly and what could be a better place than excelforum !

I have an MS Excel File (2007 version) sample file attached, which has name, designation, blood group and so on. The last column is for hyperlinking photographs of individuals.

In the same folder where I have saved this excel file, are lying photographs of individuals. While scanning the photographs, I have saved them serially i.e. 1,2,3 and so on.

In the Excel file, in last column, I have given the respective serial numbers. In order to hyperlink one has to select that particular Cell, press Ctrl K and you automatically go to the folder containing individual photographs, you select that photo and OK.

Problem :

I have to do this hyperlinking one by one and if there 1000 photos, lot of time is wasted.

Solution Needed :

Just in case of excel formula, which we copy and paste, Can I get a command by virtue of which the column titled Photo or column next to it gets automatically Hyperlinked to respective photo WHEN I copy and paste such command to all cells in that column.

Thanks a million and warm regards ::: Jack


I have a requirement to change the panes in excel.
My excel file will contain more than one tab.
I have to free the first two lines in all the tabs except the first one.
I tried the following code.

Code:

xlsobj.Worksheets(1).Rows("1:2").Select
ActiveWindow.FreezePanes = True


But in this I have to change the Active Worksheets in VBA, Which I want to avoid.
Is there any method to achieve this without selecting the cells.
Something like
Code:

xlsobj.Worksheets(1).Rows("1:2").FreezePanes = True







I am creating a basic accounting spreadsheet and I ask for assistance to automate data entry posts. I would like to have entries that are entered in the general journal automatically post to the corresponding ledger accounts. The entries need to remain in chronological order. Relative cell referencing will not work because the rows in the ledgers will not correlate to the rows in the journal because the journal but the entries in the ledger need to input on the next available row in that ledger account. Additionally, as the number of entries increase, can the ledger accounts add a new row?

Attached is a very simple example with three transactions. I have included an end state view in the ledger accounts tab.

I'm having a problem in a workbook with several ActiveX command buttons. I had been using the form control buttons to run macros, but the boss wanted each button to have it's own, different color. So I removed the form control buttons and created new ActiveX command buttons. I got into the button properties and set the background colors. I added the _Click code to run the macros when the user clicked the buttons.

All of the buttons were working fine. Then I saved and closed the workbook and went to lunch. Now when I open the workbook, the buttons don't work! When I click them nothing happens. They appear frozen. They don't even seem to click. No error message. Nothing.

If I right-click the button in Design Mode and select Properties, I get sheet properties not the button properties. I can't seem to locate the command button properties any longer. I still see the button name "cmdButtonGetInfo" and "=EMBED("Forms.CommandButton.1","") in the name box and formula bar. The odd thing is if I create a new button it works fine until I save and close the file. When I reopen the file none of the buttons work.

It's like the buttons are being disabled when I close or open the file. Any suggestions?


We have a number of Excel users in our office who cannot copy and paste
between Excel workbooks. They can copy and paste between worksheets. When
you highlight the section to copy and then go to the new workbook both the
paste
and paste special are "grayed out". This is true whether you right-click the
mouse, go to the edit menu, or use control keys. This occurs with any data
type and the most simple workbooks. I have seen some suggestions here but
none have worked for this particular problem. I have reset the menus and
renamed the .xlb files and neither helps. You can open the clipboard and the
paste will work, but there is no paste special option. Any help would be
greatly appreciated. Thanks!




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 have a workbook with 50 sheets (1 for each employee).

How can I get Excel to sort these into alphabetical order ?

i have a cell i have to check if it contains six characters. I have a list of data that i need to narrow down to six characters. I have successfully done that, but some of the cell has 5, 6, or 7 characters. The list contains about 600 cells, but i don't have time to format them individually. I want to create a formula that returns true or false if the cell contains 6 characters and false if it is above or below 6.

Can somebody help me, i'm new to excel!


Hello, I am pretty new to excel programming/messing around so I'll refer to those who are much wiser than I am. I am trying to set up a form for work, in this form I want to have a page with a bunch of cells pre-sized. What I want to do is when I insert a picture from a job site, that when this picture gets inserted, it will automatically resize to fit within the cell. I don't have time to manually resize dozens of pictures and if I could get this to work it would be awesome! I tried to search for an answer using the search function, but I kept getting a fatal error about allowable memory? Thanks in advance for you help!


Hello,

My Cell C3 is a numeric value.....I have set conditional formatting to
make the text red and bold when the number is equal or less than 10,000
is there a way I can make cell E3 display a message when the C3
condition is true?? or if not a message is there a way to make a
message box pop up when my C3 condition of less then or equal to 10,000
is true?

how would I do something like this?




after sorting data in ascending order, how do i unsort it to get back the original format? i can't find the option anywhere on the excel ribbon for this


Hello

I'm quite experienced Excel user. I've never come across this problem but tinkering in every conceivable way within Excel settings and the solution has eluded me.

I have added a worksheet created elsewhere (it is a form I need printing, with the data coming from 2 sheets I have created from scratch) which has pre formatted cells for Date and Client Name etc.

When I try to reference the cell in this added sheet from my 2 sheets, instead of the result, it always displays the formula, not the result.

I have tried doing it from one of my sheets to reference to this new, and that displays the result and not formula. I can't imagine why it's doing this and I've never seen it happen before.

Formatting cells, giving cells names rather than the usually adequate of reference to the Cell Number doesn't change things. I wonder if I've picked up some legacy protection from the original form but can't see anywhere in the tools etc that's obvious.

There's about 50+ cells that need referencing and I got to get this done for work.

Please help me. This is my first need to post on a Excel Forum as I've always found help or answers from other peeps or internet but this one is making me scratch my head big time.



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.


Corporate edict.

I have a worksheet that is locked and protected now, except for cells in a certain collumn. I have named the cells in that column "MS96A".

If a user enters a date in a cell or range of cells anywhere in the column, the changed cells also need to be locked and protected (Once they enter a date, it is not allowed EVER to be changed again. Corporate requirement! *Shrug*).

What I am looking for is this. If the user selects that cell again, they will get the usual pop-up message, "The cell or chart that you are trying to change is protected..."

I think I am close, but I am getting an "End If without block If" error on the If Clause.


Sub Worksheet_Change(ByVal Target As Excel.Range)
Dim MRange As Range
Set MRange = Range("MS96A")
' If Not Intersect(Target, MRange) Is Nothing Then For Each cell In MRange Sheets("Sheet1").Unprotect Password:="temp"
cell.Interior.ColorIndex = 3
cell.Font.Color = vbBlack
Selection.Locked = True
Selection.FormulaHidden = False
Next cell
ActiveSheet.Protect Password:="temp", _
DrawingObjects:=False, _
Contents:=True, _
Scenarios:=False
ActiveSheet.EnableSelection = xlUnlockedCells
End Sub


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!

Matt


Hi All,

I've been struggling with this for a while now and can't believe how hard it is!. I've searched on this site and on others to get some clarification but to no avail.

It's pretty simple really. I have a user form which contains a tex box for a user to input the date I want the format to be dd/mm/yyyy but can't find out how to set the format of the text box to this.

Please can someone give me a bit of guidence or link me to a good rescource if missed it in the search.

Thanks in advance.
