Title

[P] _ms_dydx_parse -- Parse dydx() specifications for postestimation commands

Syntax

_ms_dydx_parse [dydx_varlist] [, ey ex]

dydx_varlist: dydx_var dydx_varlist dydx_var

dydx_var: indepvar _continuous _factor _all *

where indepvar is any valid single variable specification that identifies an independent variable participating in the column stripe for e(b), for example, standard variables with or without time-series operators, and factor-level variables (but not interactions of variables).

_continuous is a shortcut notation that means all the continuous indepvars.

_factor is a shortcut notation that means all the factor-variable indepvars.

_all and * are synonyms for _continuous _factor.
