Your knowledge is insufficient. Your expectations are incorrect.
Either consult someone locally who has sufficient statistical
expertise or do some studying of GLM's. As this is a statistics not an
R question, you might also wish to try posting to a statistics list
instead, like stats.stackexchange.com.


reporting z-values is not very useful and the F-values together with
the p-values would be desired for the report. I tried the commands
summary(model) , anova(model) noranova.glm(model), but couldnt get the
F-values that way.
