Dear All
I'm trying to get marginal effects for a variable from a probit model, but I want them calculated for values other than the variaable mean.
Having searched the stata archive I have seen mention of a command 'dprobit2' which allows specification of the x variable at any value (see www.stata.com/users/wsribney/dlogit2/dmlogit2.hlp).
However, my version (stata 6.0) will not handle this command.
Is this an ado file and if so how do I get hold of it so I can use this command?
many thanks.
Ron Dorsey
