More than likely, you do not need to specify the nonlinear
option after an official Stata estimation command, because mfx
is smart enough to determine whether F(x) meets the linear-form
restriction. For community-contributed estimation commands, if you are
not sure whether y is in linear form, specifying
nonlinear is always a safe choice. However, nonlinear methods
take much longer than linear methods. For the definition of the
linear-form restriction, please refer to [R] mfx.
