Re: [R] iteration limit error in gamm and notExp2

Isidora, What is the actual model structure that you are trying to fit? It's not clear to me that modifying the nonExp2 defaults will help convergence here, but it may be that some slight modifications of the model itself will sort things out, which is why it would be good to know what the mod

[R] iteration limit error in gamm and notExp2

hi, I am trying to run a mixed effect gam using gamm (mgcv) and I get the following error: "Error in lme.formula(y ~ X - 1, random = rand, data = strip.offset(mf), : nlminb problem, convergence error code = 1 message = iteration limit reached without convergence (9)" I've read all about 'notExp
