Hi,
I calculate marginal effects from an estimated probit model and struggle with the XVECTOR option of the PRJ instruction. It works fine for the ATMEAN option,
prj(atmean,dist=probit),
but not if I enter the vector of means manually,
prj(xvector=||mean1,mean2,mean3,...||,dist=probit).
Shouldn't the two yield identical results?
I would appreciate any help.
