EMC: Stata module providing prefix command estimating contrasts for effect modifier values

Niels Henrik Bruun

Statistical Software Components from Boston College Department of Economics

Abstract: The prefix command emc takes a regression command as an argument. From the regression command argument emc uses the first variable as an outcome variable, the second as a dichotomous contrast variable and the third as effect modifier transformed into a function using cubic splines. The commmand emc presents an approach to model and visualise how the effect modifier affects the effect/contrast if the effect modifier is continuous. Restricted cubic splines is one way of estimating the two functions describing the outcome on the effect modifier for the exposed and unexposed, respectively.
