While I probably should have mentioned this when Stata's (relatively) new and quite helpful "fracreg" command was released, a recent surge of student questions about how to best model a rate (or fractional) dependent variable motivates this post.
Periodically ELS scholars will need (or want) to model a defendant variable that is bounded between zero and one (e.g., rates, fractions, percentages, etc.). Until recently few satisfactory options (at least "off-the-shelf" ones) existed as the various standard "reg" commands are inapt given the rate/fractional/percentage dependent variable's bounded structure. The "fracreg" command in Stata, however, is designed for dependent variables that range from zero to one (inclusive). Anyone intrigued should consult the user manual (here) and watch a brief introductory tutorial video (here).
