I agree that it would be nice to have a doubly non-central F
distribution available, and an exchange on this list from last November
suggested that the singly non-central F may not be that accurate
(http://tolstoy.newcastle.edu.au/R/help/05/11/14871.html). A brief web

Dear Professor
I have read your questions in the website on Doubly non-central
F-distribution. I am looking for source code for evaluating this
function now. I have matlab code but it's only accurate up to the 4th
decimal point. Dataplot is more accurate, but it is not user friendly as
you only
Hi Wolfgang.
I would be surprised if a doubly noncentral F-distribution function is
available (and encourage you to check its accuracy if it is). Although R
allows pf() to have a noncentral value specified, the results are not
always accurate. I posted about this about a week ago (10/24/05) and
Hello All,
Has anyone written a function for the distribution function of a
*doubly* non-central F-distribution? I looked through the archives, but
didn't find anything. Thanks!
Wolfgang
