Testing this significance of a factor in a mixed-model "ANCOVA"
R-users - I must preface this question by saying that I'm a relative newbie to both R and mixed-modeling. I'm using 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 l...
