Hello all,
I was wondering if it would be possible to use R's pt() function in
place of the pt() function in S-Plus? Unfortunately S-Plus does not
allow for a noncentral parameter in determining t probabilities from
noncentral distributions. I've heard that pasting some functions into
S-Plus from R works fine, but, in the case of pt() it doesn't.
Also, more for the Insightful people, is there any likelihood that a
function for pt() with a noncentrality parameter and especially a qt()
with a noncentrality parameter will be developed anytime soon? As of
right now I feel that biggest "thing" that is missing from S-Plus is the
lack of noncentrality capability. I realize the pchisq() and pf() allow
for noncentral parameters, but, neither of these allow for noncentral
parameters for the finding quantiles. It is frustrating because I try
to use S-Plus for all of my work, but, I am increasingly working with
noncentral distributions, which forces me to use SAS or other programs
when better noncentral capabilities.
Thanks very much,
Ken
