[NMusers] Covariate lead to increase in Eta shrinkage

Dear all,

I have a model that I am currently working on that is going through
covariate selection. There's one particular parameter, whose ETA-shrinkage
before adding any covariate was 25%. However, after adding a covariate
successfully, the ETA-shrinkage was increased to almost 80%. While the
model parameter estimation in this final model is reasonable, and there's
no warnings or errors in the output file, the increase in the ETA-shrinkage
basically means that the individual estimation falls back to population
estimation. Under such a circumstance, how should I decide if it's
reasonable to keep this parameter? Thank you.

Best Regards
