I run a tobit because of left censoring at zero, then want to use
margins to predict the marginal slope for the observable dependent
variable atotgiv.
Everything looks ok except in the output appears
Expression: E(atotgiv*|atotgiv>otherrelh), predict (ystar(0,.))
The appearance of otherrelh in this expression is mysterious. This is
another dummy variable used as a control. I didn't program it to look
at that, and I think it should read, instead, E(atotgiv*|atotgiv>0), etc.
Is this a bug? A mistake on my part? A misunderstanding?
Here is the exact command and headers for the results:
margins, predict(ystar(o,.)) dydx( earn01 assety01 welfare01
nonwelfare01 annuapprecinh annuownwealthn annuheq )
Average marginal effects Number of obs
= 4935
Model VCE : Robust
Expression : E(atotgiv*|atotgiv>otherrelh), predict(ystar(o,.))
dy/dx w.r.t. : earn01 assety01 welfare01 nonwelfare01 annuapprecinh
annuownwealthn annuheq
