Hello, thank you very much for your previous answers about the C++ code. I am interested in the application of the Gibbs Sampler in the IRT models, so in the function MCMCirt1d and MCMCirtkd. I've found the C++ source codes, as you suggested, but I cannot find anything about the Gibbs Sampler. All the files are for the Metropolis algorithm. Maybe I am not able to read them very well, by the

...ine does not allow for different Vi (variance covariance matrix of the e_i vector) matrices for each cluster. Is there an easy way to fit this model in R or should I bite the bullet and code the likelihood functions ? Also, is there an easy way to fit a Bayesian version of this ? Again there is mgibbs.lmm but it also does not allow easily for a different Vi matrix for each cluster/. Thanks, Benn --------------------------------- [[alternative HTML version deleted]]

...by group. For example: We have a share here called cs whose path is /home/cs/common. Under that directory we have /home/cs/common/ta. The "ta" directory has owner and group privs, and nothing for world. drwxrws--- 2 douglas cs21ta 512 Jun 30 16:59 ta/ Along comes a user, mgibbs. His primary group is csugrads, but he is also listed under the "cs21ta" group in the NIS group file. Under UNIX, he can look at files in the "ta" directory and create files there. But when mapping the "cs" share, he can't see any files in the directory, nor can...
