Dear Francisco,
Yes i want to model it. I want to do a missing-analysis. Dependvar is
the right-skewed and the undependvars are differed survey methods
(online vs paper and pencil) under control of gender, etc.
Dear Maarten,
thanks a lot. So, ifI understand youproperly the correct family is
gaussian?
glm av uv uv, link(logit) vce(robust)
LG,
Jörg
