Using the zero-inflated binomial in experimental designs
...Unfortunately
the function glm does not have an option to place a family of this kind I'm
about, because if I had, it would be easy, made that my goal is simple, just
wanting to compare the treatments. For that you have an idea, here is an
example of my database.

Model averaging with (and without) interaction terms
I?ve used logistic regression to create models to assess the effect of
3 variables on the presence or absence of a species, including the
interaction terms between variables and model averaging using MuMI:
model.avg
The top models (delta<4) include several models with interaction terms
and some models without; model weights are quite low for all models
(<0.25). My problem is that the models with interactions have negative
coefficients on the variables with a positive interaction term whereas...
