Model simplification in lme
Pinheiro and Bates suggest that model simplification of fixed effects in lme
with anova (model,model2)
is anticonservative. What is the best way to simplify a model in lme?
Testing the p value for each fixed
factor with anova (model, type="marginal") and removing it if it is not
significant? I know this in not a valid
approach in lm but I am not sure about lme.
Thanks to Kingsford for  pointing out the section in Pinheiro and Bates
about model simplification.
Thanks,
Mel
