With log linear I assume that you mean that you have
taken the log of y (what have you done with the 0s?)
and that the x is still in the original metric. So no
the interpretation of -mfx- with the dydx option (the
default, so in my example I just called -mfx- without
option) is the percentage change in y for a unit
change in x. To get elasticities of the form
percentage change in y for a percentage change in x,
you need to add the dyex option.
Hope this helps,
