solve cdf for noncentrality (PR#11527)
Full_Name: Jerry W. Lewis
Version: 2.7.0
OS: Windows XP Professional
Submission from: (NULL) (198.180.131.16)

If you are saying that this need is already adequately addressed in R, then

Is there are easier way to do what I'm trying to accomplish? The analog
in SAS of what I'm trying to come up with is FNONCT.
