Is this the right way to state the results: The random effect ID (likelihood ratio test; c2=12.26, d.f.=1, p=0.0005)? Is this the right way to state the results: The random effect ID (likelihood ratio test; p<0.0001)? Or should I also state the value L.Ratio?
Why would you give the value of the likelihood ratio test for lme but not lmer? And the P-value, as mentioned recently here recently (and see Ben Bolker's http://glmm.wikidot.com/faq, and Fabian Scheipl's RLRsim package) is too conservative, though it won't matter here. Cheers, David Duffy.
