Error Function Erf In Excel

the equation:For further details, see the Wikipedia Error Function page Basic DescriptionThe Excel Erf function calculates the Error Function, integrated between two supplied limits.The syntax of the function is:ERF( lower_limit, [upper_limit] )where the arguments are as follows:lower_limit-The lower limit of the integral.[upper_limit]-An optional argument which, if supplied, gives the inverse erf function excel upper limit of the integral.If the [upper_limit] argument is omitted, the integral between 0 erf error function ti-89 and the supplied lower_limit is returned.Improvements in Excel 2010The Erf function has been improved in Excel 2010 in that it can

now accept negative function arguments.In Excel 2007 or earlier, if you input a negative value for the upper or lower limit, the function would return an error. However, in Excel 2010, the function algorithm

has been improved, so that it can now calculate the function for both positive and negative ranges.Erf Function ExamplesIn the following spreadsheet, the Excel Erf function is used to calculate the Error Function integrated between different limits.Formulas:AB1=ERF( 0, 1.5 )- error function integrated between 0 & 1.5 2=ERF( 1.5 )- error function integrated between 0 & 1.5 3=ERF( 1, 2 )- error function integrated between 1 & 2 Results:AB10.966105146- gaussian erf error function integrated between 0 & 1.5 20.966105146- error function integrated between 0 & 1.5 30.152621472- error function integrated between 1 & 2 Note that, in the above spreadsheet, the functions in cells A1 and A2 perform the same calculation - i.e. the integral between 0 and 1.5.Further examples of the Excel Erf function are provided on the Microsoft Office website.Erf Function ErrorsIf you get an error from the Excel Erf function this is likely to be one of the following:Common Errors#NUM!-Occurs in older versions of Excel (Excel 2007 or earlier), if one or both of the supplied arguments are negative.#VALUE!-Occurs if one or both of the supplied arguments are non-numeric.

Neither are working. I keep getting the error Compile Error: Sub or Function not defined. However, if I go into a cell and manually try to use the error function, it works. Why is that? How can I use it in my actual code? The error function is ERF(x) and the complimentary error function is ERFC(x). Here's an example of things that don't work: Sub SeriouslyWHYIsntThisWorking() x = 3 error function erf Range("A1") = Erf(x) End Sub Even this doesn't work: Sub PleaseWork() Range("A1") = Erfc(1) End Sub But if I went into Excel and typed =ERF(3) or =ERFC(1) into a cell, it'll work. I'm very new to this and probably missing something incredibly simple. Help would be greatly appreciated! excel vba excel-vba share|improve this question edited Jul 23 '12 at 21:31 Gaffi 3,12862859 asked Jul 23 '12 at 21:04 TheTreeMan 32161429 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted To use a worksheet formula in vba, you need to put Application.WorksheetFunction. in front of it. Some functions do have vba equivalents, but (as far as I know) not in the case of erf and erfc share|improve this answer edited Jul 23 '12 at 21:21 answered Jul 23 '12 at 21:12 SeanC 11.1k52045 Oh, I had no idea that not all of them had vba equivalents. Thank you! –TheTreeMan Jul 23 '12 at 21:18 example: =FIND(: while you could use application.worksheet.find(, it would be better to use the vba function InStr –SeanC Jul 23 '12 at 21:20 1 This still doesn't address the need for the add-in to be installed. –Gaffi Jul 23 '12 at 21:28 add a comment| up vote 3 down vote Do you have the Analysis Toolpak for VBA add-in installed/r
the inverse error function erf(x)=0.8 <=> x=inverf(0.8) <=> x=0,90469 Currently i am using the goal seeker, but i know that matlab has a erfinv function - does excell have one? if not - does anybody know about som java-coding that can do it Best regard morten Morten, Apr 1, 2004 #1 Advertisements Jerry W. Lewis Guest inverf(p) = SQRT(GAMMAINV(p,0.5,1)) inverfc(p) = -NormSInv(p/2)/Sqrt(2) Mathemetically exact, but not necessarily numerically good in versions prior to 2003.
