Hello! I have a data set where i need to predict hotel stays in a 3 month period by customer. I have stays for each customer in the 3 month period and the previous 3 month period + other variables. these stays contain an integer that ranges from 0 to 10. classic poisson distribution.
my question is around zeros. usually we could take logs on the stays and run an OLS model i think an enhancement would be to fit a poisson GLM model. i am confused about handling of zeros. i will have zero values on the RHS and potentially on the LHS. It seems like the poisson GLM model can handle zeros on the LHS and RHS. i guess my question is fitting a poisson GLM, are zeros allowed? If so, how is this estimated with a log link function? -zubin ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
