Hi all:
Here's a question about result of loglinear analysis.
There're 2 factors:area and nation.The raw data is in the attachment.

I fit the saturated model of loglinear with the command:
glm_sat<-glm(fre~area*nation, family=poisson, data=data_Analysis)

After that,I extract the coefficients:
result_sat<-summary(glm_sat)
result_coe<-result_sat$coefficients

I find that all the coeffients are 1 or very near to 1.

How does this happen?Why all the coeffients are 1 or very near to 1?

Thanks!

My best
