I am trying to run a mediation analysis in Stata 12 using the "sem" command. The dependent variable is a continuous variable which is left-censored. The mediator is a ordinal variable with 5 levels and the independent variable is a log-converted continuous variable.
I am getting significant results when I run the regressions separately: (a)
the tobit regressions on the dependent variable, and (b) ordered logit regressions with the mediator as the dependent variable. I would like any thoughts as to how to combine them. I did a Google search, which pointed me to the MPlus command.
Thanks,
VJ
