Here is the link to Jim Weigang's APL version. http://www.chilton.com/~jimw/fdist.html I've converted the html material to APL using his APLASCII workspace and they work fine in APLWIN. If anyone wants this workspace I'll be happy to email it. Anyway, these are not "high precision" in the sense of the Extended_Precision_Functions but for my application, extended precision is not necessary. All I want to do is compute critical values of the F distribution in my statistics class. My class is using Release: J5.03.

If you can provide a link to Jim Weigang's APL function perhaps members of the Forum can translate it. I have some thoughts of doing more of the standard functions in http://www.jsoftware.com/jwiki/Essays/Extended_Precision_Functions The F distribution and the inverse F are currently not in the list. ----- Original Message ----- From: "Howell, Leonard" <[EMAIL PROTECTED]> Date: Sunday, March 4, 2007 3:08 am Subject: [Jprogramming] Inverse F Distribution > Anyone have J code for accurately computing the inverse to the > cumulative F distribution?
