f_able: Estimation of marginal effects for models with alternative variable transformations

London Stata Conference 2020 from Stata Users Group

Abstract: margins is a powerful post-estimation command that allows the estimation of marginal effects for official and community-contributed commands, with well-defined predicted outcomes (see predict). While the use of factor variable notation allows us to easily estimate marginal effects when interactions and polynomials are used, estimation of marginal effects when other types of transformations such as splines, logs, or fractional polynomials, among others, are used remains a challenge. This paper describes how margins capabilities can be extended to analyze other variable transformations using the command f_able.
