[R] Have problem to do loop to generate transformed chi-squared variates
Hello R-helpers, I need to generate standard variates normal to 'create' chi-squared variates. To make you more understand, (1) a<-rnorm(3,0,1) *after do (1), I need to squared and summed the three values. My problem is, how am I going to continue the programming if I had to repeat the process for 15 times, which in the end I will get 15 values from the whole programme.Hope you can help. Sincerely, Agnes [[alternative HTML version deleted]]

Hi Agnes, I think this is likely homework, right? If that's the case, we're really not supposed to give you help. If not, why not simply use rchisq to generate chi-sq variates exactly?

Homework? We don't do people's homework for them.
