Hi,

I am fitting a semiparametric generalized linear mixed effect model with a DP

prior on the random effects and I use a truncated approximation of the DP. If

I add a prior on the mass parameter of the DP, after several iterations I

obtain this error message:

Errore: RUNTIME ERROR:

Singularity in likelihood found by Slicer

What does it mean? Where is the problem?

Thank you for your help,

Jacopo
