Dear All

Where can I lookup good methods to compute
p from q=bin(m,n)p^n*(1-p)^(m-n) such that
q<=alfa, alfa small. Are there such libs,
code and source in R?

Best Regards

 eta<-glm(cbind(n,m-n)~1,family=binomial)$coeff
 exp(eta)/(1+exp(eta))

would work ;-). I am not sure how "good" it is.

I can't quite tell from the description whether you're looking for the
CDF or PDF of the binomial distribution or of the beta distribution: the C
code for these functions (qbinom.c, pbinom.c, qbeta.c, pbeta.c) lives in
the src/nmath directory.
