Hi all,

I am working with the R package 'quint' to test for qualitative treatment-subgroup interactions (personalized medicine). Everytime I analyze my data there are some warnings which I cannot handle. All warnings are of the same sort. Actually, the main problem is that I do not understand what the warning means exactly:

Warning messages:

1: In computeD(tmat[kk, 1], tmat[kk, 2], tmat[kk, 3], tmat[kk, 4], :

value out of range in 'gammafn'

Is anybody well versed in this R package or is it probably an universal warning that you were confronted with in another context? I do not know what 'gammafn' could be and why the value is out of range.

I appreciate any comments and ideas!

Best,

Brian
