W. Lewis, Sep 14, 2004. Jerry W. Lewis Guest No, but you can use the relationship between erf and statistical distributions to fake it. erf(x) = GammaDist(x^2,0.5,1,True) so erfinv(p) = Sqrt(GammInv(p,0.5,1)) erfc(x) = ChiDist(2*x^2,1) so inverse error function excel 2010 erfcinv(p) = Sqrt(ChiInv(p,1)/2) The ChiDist function is much more accurate for large x than calculate inverse function wolfram alpha the ATP erfc function. The Inv functions are useless for p's associated with x > 3.5 in Excel versions prior to how to calculate inverse function on ti 84 2003. Jerry fv wrote: > subject line says it all! Jerry W.

If x is the mean and y is the std dev I know that CI=(x-ny,x+ny), where n=sqrt(2)*inverseERF(CI). I tried to make a vba function to calculate the invERF, but I'm off by a bit. inverse error function Does anyone know of an existing invERF funcion? I can't find actual code for one anywhere.

There is also a CONFIDENCE function.

If, however, you really need to compute the value of the invERF there is a small code (posted by JJ 05-18-06 09:20). It is in Pascal and so should be very easy to port to vba. The name of the function is invErf http://les-mathematiques.u-strasbg.f...86277&t=286277 Hope this helps PGC Share Share this post on Digg Del.icio.us Technorati Twitter Reply With Quote Nov 17th, 2006,01:34 PM #4 pete6982 New Member Join Date Aug 2006 Location Louisville, KY Posts 19 thanks guys. i was able to recode the pascal invERF function into vba.
