denominator degrees of freedom and F-values in nlme
...istribution, estimating theta based upon a glm
without individual as a random effect). My data set will not be
balanced, with varying numbers of measurements taken on different
individuals and some individuals have no weight measures just a
morphological type.
My output:
denDF numberdf
Intercept 495
weight 232 1
horn type 495 1
horn type:age 232 4
So my question is where do these denDF come from and how are they
calculated? I wish to then test significane of these fixed effects and
can get F-ratio's and P-values but are these appropriate?...
