Re: st: functions for computing prob

I am computing probabilities for t-test and z-test.
I want to know if the functions -tprob- and -normprob- are out-of-date
since no help files explain these functions. Are -ttail(n,t)- and -normal(z)
right functions to compute probs?
see -help density functions-
or -help functions-
Yes, the cumulative normal density function, normprob(), still works but is out
of date, no longer documented, and has been replaced by normal(). Am not sure
whether tprob() ever existed? - doesn't seem to work and is not documented in
any case. ttail(n,t) is documented under help for functions.
