Dear R-helpers, I am trying to use general location model for a set of category and continuous variables (medical dataset). Does any one know where I can find this kind of R source code???? Mix package (R code) has functions for restricted and unrestricted general location models, but it seems that they can only handle datasets with missing values (????). My dataset has no missing value, so I did not success in using this package to handle my dataset. Any one has experience in this. By the way, if I assume that my dataset has one missing value, then I can use the functions in mix package to build up location model! Thanks ping
