SHAPLEY2: Stata module to compute additive decomposition of estimation statistics by regressors or groups of regressors

Programming Language



Shapley2 is a post-estimation command to compute the Shorrocks-Shapley decomposition of any statistic of the model (normally the R squared). Shapley2 can be used for most estimation commands, e.g. ols, probit, logit, oprobit. Compared to the user written command shapley, shapley2 is faster and enables you to compute the Shapley value by groups of variables. The results are stored as e()-matrices, allowing the user to use them afterwards, for instance to export them to LaTeX.
