poisson regression

It would be a big help if someone could give a practical example (by hand) how Poisson regression is used to calculate a time trend line, and calculate a confidence interval for whether there is a trend. Here is some sample data if you would like (Texas viral hepatitis deaths): Year, Events...

Hello, I've been reading some public health papers and they account for demographic factors such as age, gender, and race in regression models (poisson/negative binomial) where the outcome is daily/monthly rates. Considering that the demographic factors are at the individual level and rates...

I'd like to know how several variables are related to the number of small-scale slaughterhouses at the county level throughout the US. There are over 3000 observations. By far, most counties vary between 0-2, but there is a small handful of higher population areas with many more. LA is the...

Hi folks: I'm trying to apply cross-validation of models (e.g. the paper "On Cross-Validation of Bayesian Models" by Alqallaf and Gustafson) in the context of count data and have run into an interesting problem. My understanding of how such cross-validation should work is that one draws...

Hi all, I'm currently analyzing data from a series of behavioral experiments that all use the following measure. The participants in this experiment are asked to select clues that (fictitious) other people could use to help solve a series of 10 anagrams. The participants are led to believe...

Hi, I read that Poisson regression is used when the dependent variable is a "count". But what if both the dependent and the independent variables are counts? Should you still use a poisson regression (assuming that the dependent variable has a poisson distribution)? thanks:)

Hi I fitted a log linear model (proc genmod dist=negative binomial link=log) to see any dependence/association between 3 categorical variables. I know how to evaluate the best model but i have difficulty to explain the following output. parameter p-value...
