I've never replied before so i hope this goes through... I usually just use the non-central f distribution directly
p1<-pf(qf(SIG, df1= D1, df2=D2, , 0,lower.tail = FALSE),df1=D1,df2=D2, NCP,lower.tail = FALSE) Where I derive or estimate the non-centrality parameter from the Expected Mean Squares. But there are also some packages that will so simple power calcs for t tests and anova On Sun, Jan 11, 2009 at 3:00 AM, <[email protected]>wrote: > Send Bioc-sig-sequencing mailing list submissions to > [email protected] > > To subscribe or unsubscribe via the World Wide Web, visit > https://stat.ethz.ch/mailman/listinfo/bioc-sig-sequencing > or, via email, send a message with subject or body 'help' to > [email protected] > > You can reach the person managing the list at > [email protected] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Bioc-sig-sequencing digest..." > > > Today's Topics: > > 1.
