I am currently exploring mclust to do clustering by Gaussian mixture modeling. There are typically 1-5 clusters in my datasets. In the latest version of mclust (version 3), there is now the ability to specify priors. However, I am confused about the implementation. I've read through the documentation about priorControl() and defaultPrior() which describe the specification of a single prior for a dataset. But I often have a prior for all of my clusters -- how do I specify that, i.e. give the program multiple means and multiple covariance matrices for where I believe the clusters will be a priori?
