• Resumen

  • Dominance analysis is a common method applied to statistical models to determine the importance of independent variables. In this article, I describe two community-contributed commands, domin and domme, that can be used todominance-analyze both independent variables and parameter estimates in Stata estimation commands. I discuss how to compute dominance statistics, providemultiple examples of each command applied to data, and outline how to interpret the results from each data-analytic example. I conclude with computational considerations for users applying larger models.
