Query: Bartlett corrections in beta regression models   We consider the issue of performing accurate small-sample testing inference
in beta regression models, which are useful for modeling continuous variates
that assume values in $(0,1)$, such as rates and proportions. We derive the
Bartlett correction to the likelihood ratio test statistic and also consider a
bootstrap Bartlett correction. Using Monte Carlo simulations we compare the
finite sample performances of the two corrected tests to that of the standard
likelihood ratio test and also to its variant that employs Skovgaard's
adjustment; the latter is already available in the literature. The numerical
evidence favors the corrected tests we propose. We also present an empirical
application.
