Details

The levels of varb indicate nodes of the graphical model to which the corresponding elements of the response vector resp belong. This is the typical long format produced by the R reshape function. For each individual, there are several response variables. All response variables are combined in one vector resp. The variable varb indicates which original variable the number was for. The variable id indicates which individual the number was for. The levels of varb, which are the names of the original variables are [object Object],[object Object],[object Object]
