Dear R users,
Is there any package that I could use to perform Penalized Logistic
Regression (i.e. Ridge/Lasso regularization) including also an offset term
in the model (i.e. a variable with a known coefficient of 1 rather than an
estimated coefficient)? I couldn't find any package that would allow using
offset terms.
Did you try the strategy suggested by the posting guide? viz.
RSiteSearch( "penalize logistic offset", restric='functions' )
Works like a charm!
HTH,
Chuck
Any guidance will help.
Many thanks!
Axel.
