Re: [R] Multivariate chi-square distribution function

Hello If you want the multivariate t-distribution, use rmvt() of the mvtnorm package. If you want the Wishart distribution, one can write a little nonce function: library(mvtnorm) rwis <- function(n,sigma){ crossprod(rmvnorm(n,sigma=sigma)) } I'm not sure what you mean by the multivariate gam

Dear All, Is there any function in R for computing "multivariate chi-square distribution"? How about "multivariate gamma distribution"? I appreciate any comment on this subject. Thank you, Amin Zollanvari PhD student Department of Electrical and Computer Engineering, Texas A&M University, Coll
