1 continuous non-normal variable ~ 4 factors + 1 continuous covariate (with interactions)
Im struggling on something... I have one continuous variable (A), and I need to explain it with 4 factors, and maybe one continuous covariate. And of course, my variable A is not normal at all (it's a duration in seconds, whole numbers). What can I do? I would know how do deal with it if I had one factor, maybe two, but in that case Im really not sure what I am supposed to do to write a model that is statistically correct.
If you are working with a positive outcome variable, one approach is to use glm( ..., family ="Gamma"), other approach is to use survreg() in the package survival. Cheers, Pablo
