Subject: [R-sig-eco] Post Hoc tests GLM
Dear Fellows,
I am trying to build a model in order to test the influence of the time of
the day, on sex and behavioural category. After performing several
modelations I chosen the best model which is
glm(formula = Frec ~ Group+ Hour:Category, family = poisson)
summarizing I have
Df Deviance Resid. Df Resid. Dev Pr(>Chi)
NULL 41 6027,36
Group 2 6,15 39 6021,21 0,0462
Category:Hour 13 5972,08 26 49,13 <0,0001
I found significative effects of sex and behaviour:time interaction.
Nevertheless I am having lot of troubles in order to make post hoc
comparison, specially in the case of Group. Does somebody know how to
perform post hoc comparisons when using GLM, if so I would really
appreciate it.
Thanks in advance for your help
