Dear R User, I am wondering if there is a way to generate correlated multivariate non-normal distribution? For example, I want to generate four correlated negative binomial series with parameters r=10, p=0.2, based on the correlation...
Thanks a lot, Dennis. The reason I am not using lme4 is that its estimated variance component seems not desirable. If you use my simulated data and run the following line glm2 <- glmer(y~1+(1|alpha)+(1|beta),family...
Thanks, Enrico and Harold. I have searched the archives for this topic, but all I can find is about the multivariate normal or uniform generator, which doesn't help in my case. Harold's transformation is good for getting the...
Dear R users, I am currently doing a project in generalized mixed model, and I find the R function glmmPQL in MASS can do this via PQL. But I am a newbie in R, the input and output of glmmPQL...
Dear Reinhold, Thank you very much for pointing out my typo. Yes, I should use rnorm(n*m*k,0,sigma.e) instead of rnorm(1,0,sigma.e). The reason I not included the random error in the exponential...
