dear list!
i have run several glm analysises to estimate a mean rate of dung decay
for independent trials. i would like to compare these results
statistically but can't find any solution. the glm calls are:
dung.glm1<-glm(STATE~DAYS, data=o_cov, family="binomial(link="logit"))
dung.glm2<-glm(STATE~DAYS, data=o_cov_T12, family="binomial(link="logit"))
as all the trials have different sample sizes (around 20 each),
anova(dung.glm1, dung.glm2)
is not applicable. has anyone an idea?
thanks in advance!
ps: my advisor urges me to use the z-test (the common test statistic in
my field of research), but i reject that due to the small sample size.
