Perhaps if you followed the posting guide and did not send HTML mail
your tables would be readable. But your anova call seems wrong, as
you have the models in decreasing not increasing order.
The correct result is (computing F test by hand)
23.1814/93
[1] 0.2492624
1.5475/3

Hi,
I'm working on fitting a glm model to my data using Gamma error structure
and reciprocal link. I've been using dropterm (MASS) in the model
simplification process, but the F values from analysis of deviance tables
reported by dropterm and anova functions are different - sometimes
significant
