Hi Ben and HS,

❝ Interesting! But as I said above right now I cannot confirm which algo R. Lenth implemented into FARTSSIE. David’s statement ‘Dr. Russel Lenth generously provided the library subroutines to calculate non-central distributions (NCt)’ is not telling.

From a quick look at the code snippets, This code (in particular the function called 'tnc') corresponds to the 'NCt' function of Fartssie's module 1.
I could not find an implementation of AS 184 for comparison (anyone has a link? I googled a little but did not do much else to find it). I would say that to my untrained eye it looks like Fartssie emulates some bits of the AS 243 routines.
