Speaking Stata: The statsby strategy

Nicholas J. Cox

Abstract.   The statsby command collects statistics from a command yielding r-class or e-class results across groups of observations and yields a new reduced dataset. statsby is commonly used to graph such data in comparisons of groups; the subsets and total options of statsby are particularly useful in this regard. In this article, I give examples of using this approach to produce box plots and plots of confidence intervals.
