Im running an investigation into how unhealthy lifestyles (obestiy,
smoking etc) effect health service usage and ideally id like to use a
count analysis to do this. However im not sure whether as with OLS
analyses you can include interaction terms e.g. y = B0
+B1(X1)+B2(X2)+B3(X1*X2) where X1 and X2 are binary variables. Is this
possible using count data?
