Dear StatalistDear Peter,
I am trying to do marginal effects after oprobit. I have run a oprobit regression on a dependent
variable, which is called price3. Its other
are price2 and price1, which obviously I have not
used. So after I have run
. oprobit price3 x1 x2 x3 I issued the command
. mfx compute, predict(outcome(3))
the message I got was put a value of price3 or
or worde to that effect
so I tried
. mfx compute, predict(outcome(#3))
the message I then got was there is no category 3,
there are only 2 categories.
I suspect, this is because this price3 itself is
categorised under 0 and 1. 0 is people who do not
think price is important and 1 is for people who
price is important.
so I ran a marginal effects using
.mfx compute, predict (outcome(#2)
All I should want is M.E. of price3 is it not? as I
have run the oprobit using that variable. So I ran
. mfx compute, predict(outcome(#2))
Is that the right thing to do, as I want the M.E.
the regression I ran with the dependent variable as
Please confirm, if I am doing it correctly.
Please let me know if you need further clarification.
Thanks in advance
