comparing 3 levels of fixed factor in lme4
Obermeier Andrew · Jul 29, 2012 · r-sig-mixed-models

In lme4, in models with 3 levels of the fixed factor, each of these gets a t value comparing it to a reference level. How is this done? It is my understanding that the t value can only be used...

Hello, I just joined this list today, so am worried about proper protocol, but would like to post a question about lme4. In Baayen, Davidson, and Bates (2008), Mixed-effects modeling with crossed random effects for subjects and items, the...

Thank you very much Professor Dalgaard. I'll get the books by Maindonald & Braun and also Faraway, and meanwhile read the pdf you suggested. Yes, MEMSS is a bit difficult for me. I'm very sorry for all the noise...

3-level fixed factor in lme4
Obermeier Andrew · Sep 12, 2012 · r-sig-mixed-models

Hello Mixed Modelers, I came to this list with a question a couple months ago, and will admit it was a very humbling experience. There were a few kind responses, but my question was mostly ignored or I was told...

Obermeier Andrew · Jul 30, 2012 · r-sig-mixed-models

Thank you John Maindonald. For more than 2 levels of the experimental condition, I learned that usually we find an F to test mean differences across the levels of the condition. In lme4, the model summary reports a t value...
