Testing this significance of a factor in a mixed-model "ANCOVA"
...lme fit an ANCOVA-like model. My data consist of bone
length measurements for a developmental series of two capuchin monkey
species. I'm interested in whether the rate of bone length scaling
to body mass (i.e., growth) differs between species.
My call to lme looks like this:
model=lme(lghumlen ~ species + lgbmkg, random= ~ lgbmkg | id,
correlation=corCAR1(), weights=varExp())
where lghumlen is the log of humerus length and lgbmkg is the log of
body mass.
If I ask for a summary of my model, I get this from the table of
fixed effects:
Fixed effects: lghumlen ~ species + lgbmkg...
