Get Values For Trendline To Populate In Cells?
Dec 4, 2012I have been doing some statistical anaylsis in excel and have been using trendlines within scatter charts quite a bit.
I know excel can display the equation of the line as well as the r-squared on the chart. Is there any way to get the values for the trendline to appear in a cell next to the corresponding chart data? Of course, I can simply enter the formula myself that is given on the chart, but I am wondering if there is a way to do it automatically.
I have included the data below along with the trendline value that I calculated by manually entering the formula from the scatter chart.
Code:
YXTrendline Value
$78.990.53$79.79
$78.730.53$79.73
$80.550.52$80.88

Calculate 2nd Degree Polynomial Trendline Coefficients In VBA Without Using Cells
Jul 17, 2014i have a function in a cell (that works) to extract coefficients from a range of cells in a workbook:
VB: =INDEX(LINEST(CP25:CP27,CQ25:CQ27^{1,2}),1)}
i have variables for cp25:cp27 and cq25:cq27 already defined in my vba code. the values for these in the case i am working on are as follows (returns 110.5):
cp25 = 560
cp26 = 570
cp27 = 580
cq25 = .414
cq26 = .479
cq27 = .536
1) how to do this function in VBA only - this is part of a UDF and cannot have any helper cells
2) how to refer to 560,570,580 as a 'range'. is there a way to put these six variables into my ranges for later processing?
All of the google searches i have deal only with linear regression, taking from existing graphs, or say to just use the function i have above.
I have tried
VB:
Var = Application.WorksheetFunction.LinEst(Sheets("references").Range("CP25:CP27"), Sheets("references").Range("CQ25:CQ27^{1,2}"), 1)
[COLOR=#333333][/COLOR]
but return #value! errors. when i remove the ^{1,2} portion, i do return a value but it is incorrect (returns 160), what is the correct syntax for adding in the ^{1,2}? if you do that would be fantastic, but brings me back to issue #2 in that i need to refer to my variables in the vba code and not this range (as they will eventually be going away).
Using If Statement For Cells With VLOOKUP Equations
Mar 17, 2014I have two cells with the following equations:
H3=IFERROR(VLOOKUP(A3&TEXT($A$1,"m/d/yyyy"),'CLABSI_Raw'!$A$1:$M$300,13,FALSE)," ")
I3=IFERROR(VLOOKUP(A3&TEXT($A$1,"m/d/yyyy"),'CLABSI_Raw'!$A$1:$M$300,10,FALSE)," ")
In an adjacent cell, I am trying to use an if statement
J3=if(and(H3<1,I3<1),"yes","no")
I am not getting a return in cell J3.
Excel 2010 :: How To Exclude Colored Cells In Addition Equations

I am building a spreadsheet to keep track of my monthly spending, and debt balance. I keep track of the total amount of bills I pay each month. As I pay them, their respective line is highlighted green in the spreadsheet. I would like to create a macro/formula which would sum the remaining cells in the column which are not highlighted to display the remaining monies which need to be paid out. I'm not sure if this matters but I am using office 2010.

Linest Different From Trendline
Jan 22, 2009I am using Excel 2007. I have two sets of data. y-series is 58.61, 58.66, 58.71 and 58.76. x-series is 0.8313, 0.8309, 0.8305 and 0.8301.
I am trying to fit a quadratic function to this data. When I plot a curve and fit a trendline I get the coefficients for the equation ax^2+bx+c
a=1.3939e-11
b=-125
c=162.5225
The plotted line seems to fit the data fairly well.
However, I want to use the linest function and I am using the formula:
=INDEX(LINEST(B2:B5,A2:A5^{1,2}),1,1)
I change the index column number as appropriate to get the coefficients:
a=-75.23775
b=0
c=110.603763
The coefficients from linest seem to be way out. how I can get the output from linest to be the same as the trendline?

Copy Trendline Values To New Sheet
Apr 25, 2006I need VBA to copy the values from a treadline output box on a chart to a new sheet. The macro recorder produces the code below, but I need to make the 5th line generic so that the code will apply to any workbook. The code below will not run without the "Windows("Test.xls").Activate" statement, which restricts the code to a workbook of a specifc name (Test.xls). How can I make this run for any workbook name?
Sub CopyTreadlineData()
Sheets("A").Select
ActiveSheet.ChartObjects("Chart 1").Activate
ActiveChart.SeriesCollection(1).Trendlines(1).DataLabel.Select
ActiveWindow.Visible = False
Windows("Test.xls").Activate

Compents Of Chart Trendline Equation
Jun 7, 2008I'm in the middle of designing a sheet that (amongst many other things) takes the equation of a graph trendline, pastes it, and calculates the various values along it. I can do it by hand, but when I try to record a macro, it doesn't register that I've highlighted the equation and hit copy. Here's the code I'm working with:
Sheets("Graphs").Select
ActiveSheet.ChartObjects("Chart 1").Activate
ActiveChart.SeriesCollection(1).Trendlines(1).DataLabel.Select
Selection.Copy
ActiveWindow.Visible = False
Windows("Copy of HRA Design calculator1.xls").Activate
Sheets("Binder @ max. stability").Select
Range("A1").Select
ActiveSheet.paste
The problem is line 4 - it can't copy because the text isn't selected.
Determine The Percentage Rate Of Change In A Trendline
Feb 13, 2009I'm trying to determine the percentage rate of change in a trendline. I've got a sales chart with 90 days worth of sales figures. I can see that the trendline is trending down, but I'm not sure exactly how much.
If you take the first data point in a trendline and subtract it from the last data point and then divide that by the first it should give you the percent change. Excel must be able to do that math for you but I can't even figure it out to save my life. I can't even figure out how to display the first and last data point much less the "rate" of change I'm looking for.
Chart Trendline To Trend Only Specific Values
Oct 3, 2006i have a workbook that contains a series of worksheets. the workbook is a master document list. the first worksheet contains no data. the remaining worksheets are arranged so that A1 has the document number, A2 contains the document title, and A3 contains the review date. Id like to create a search macro that can search for the string entered into textbox1. if this is a number, the macro should search A1:A50 of all but the first worksheets in the workbook, and if its text, the macro should search B1:B50 of all but the first worksheets.
the macro should then select the cell containing what was searched. then id like the macro to prompt me and ask if id like to modify the reviewed date to todays date. d like to be prompted to continue searching for other records if they exist, and after that loop has finished to set the focus back to the search textbox.

Above is the polynomial equation of a trend line as shown on my chart, I have extracted the numbers into separate cells using LINEST, so now I have in cells A20 to E20 the numbers 1.083333333, -7.333333, 16.416667, -6.16667 and 4 respectively.With a "y" value of 25 how do I go about solving for a value of "x".
I've been stubbornly struggling with this on and off for a couple of weeks now and I'm not getting any closer to working it out and the websites I've found explaining the procedure all seem to go over my head by the time I get into the fourth or fifth paragraph.

May 12, 2014I have a macro that I run repeatedly in a certain type of spreadsheet that does an export on a selection, pulls up a "Save As" message box and saves as a text file. There are 9 sheets in the workbook that contain the same data analysis for a set of samples, the only difference between them being the number of data (e.g. some may have 1500, 1400, 1600, etc.). I only select three columns of data to export (I6:K????) that contain counts (1,2,3,....), x-coordinates and y-coordinates. The counts column (I) uses a formula that only counts if there is an x-coordinate next to it (Col J).
[Code].....
Generally, what I do to make quick work out of selecting the variable ranges is to select Sheets 03-11 (the first nine sheets) and select K6:I6 (starting w/ K6). Then, on each individual sheet, I do CTRL+SHIFT+DOWN to select all the relevant data (if I started my selection with I6, then it would select all cells that contained formulas which may or may not have x,y-coordinates adjacent to them). Once the data is selected (I6:K????), I run the export macro and save the data as text. I would like a macro that can automate the selection for each Sheet 03-11, excluding Sheets "all", "data" and "summary", and run the export macro, first prompting me for a file location and a file prefix. When the text file is saved, it uses the file prefix and Worksheet name to build the filename, i.e. "pathprefix_wkshtname".
I've attached an example workbook : 20120511_Au-cit_pH5_test.xlsx
Export Variable Range As Txt File. Ommit Error Cells
Oct 30, 2006In the attached file, I have two columns (A and B) and the column A will vary within the range from A4:A104 and column B will vary according to A. Nevertheless column A has #N/A error which is mandatory for chart. So I am looking for a macro to do the following:
Start with cell B4 and go until value exsists for "B" (let me say for eg. B40) and select the range A4:B40 and ask the user to give name for the export file export only that selection as a tab delimited txt file.

Solving Polynomial Equations
Feb 16, 2007I don't actually own Excel as yet - but I'm wondering if someone could tell me whether Excel is capable of solving what I'm told are 'polynomial equations'. An example of the sort of equation I hope to solve is: d/(1.18 + d) + d/(1.86 + d) + d/(9 + d) + d/(8.8 + d) = 2
d=? {I happen to know d = 3.65(approx) in this example btw}
Often there will be many more than four terms...
