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 - inverse erfc calculator does excell have one? if not - does anybody know about som java-coding
Erfinv Excel
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)) erfcinv excel inverfc(p) = -NormSInv(p/2)/Sqrt(2) Mathemetically exact, but not necessarily numerically good in versions prior to 2003.

- ERF (i.e. 1 - Error Function), and is given by the equation:For further information, see the Wikipedia Error Function page Related Functions:ERFERFC.PRECISEBasic DescriptionThe Excel ERFC function calculates the Complementary Error Function, integrated between a supplied lower limit and infinity.The syntax of the function is:ERFC( x )where x is the lower limit of the integral.Improvements in Excel 2010The Erfc function was 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 argument, x, 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 values of x.Erfc Function ExamplesIn the following spreadsheet, the Excel Erfc function is used to calculate the Complementary Error Function integral for three different lower limits.Formulas:AB1=ERFC( 0 )- integral between 0 and ∞2=ERFC( 0.5 )- integral between 0.5 and ∞3=ERFC( -1 )- integral between -1 and ∞Results:AB11- integral between 0 and ∞20.479500122- integral between 0.5 and ∞31.842700793- integral between -1 and ∞Further examples of the Excel Erfc function are provided on the Microsoft Office website.Erfc Function ErrorsIf you get an error from the Excel Erfc function this is likely to be one of the following:Common Errors#NUM!-Occurs in older versions of Excel (Excel 2007 or earlier), if the supplied value of x is negative.#VALUE!-Occurs if the supplied value of x is non-numeric.
