Dear list, I would like to do some simulation with a truncated multivariate t-distribution. I found "rtmvt" in package tmvtnorm. I am not sure how to specify the degrees of freedom parameter. I estimated the mean vector (with 6 elements) and covariance matrix (6 X 6) from a dataset with 46 subjects. Now I want to simulate 100 subjects. So the degrees of freedom should be 46-6=40 or 100-6=94 or some other value? Thanks a lot. Jun Shen Seventh Wave Labs [[alternative HTML version deleted]]
