Subject   st: Confidence interval in natural units after GLM with log link

Hi listers,

I am using GLM model with log link and gamma family for cost data. Covariates include treatment variable (1 for new treatment, 0 for old). What would be the best way to obtain cost difference in natural scale, the confidence interval around it and the p-value? I understand one option is to predict costs for the two arms and take the difference and estimate the confidence interval by bootstrap method. Is there another way to do it (parametrically or non-parametrically)?


Any advice would be appreciated.

Thank you
Shehzad
