Re: [R] Error with stepwise models selection using NADA library

I'm assuming that you're referring to MASS::stepAIC. There's a few problems here. Firstly, I don't think stepAIC is compatible with S4 objects. My first strategy was to create another class. However, that requires many new methods. (And the stepAIC documentation doesn't say what methods are neede

[R] Error with stepwise models selection using NADA library

Hi, I'm working with environmental data which are left-censored and I found the R package NADA which seems to do the job. After fitting a complete model, using the cenreg function,I'd like to do a stepwise procedure to minimize the AIC using the stepAIC function. Unfortunately, after fitting the m
