ZOIB: Stata module to fit a zero-one inflated beta distribution by maximum likelihood

Maarten Buis ()

Statistical Software Components from Boston College Department of Economics

Abstract: zoib fits by maximum likelihood a zero-one inflated beta distribution to a distribution of a variable depvar. depvar ranges between 0 and 1: for example, it may be a proportion. It will estimate the probabilities of having the value 0 and/or 1 as separate processes. The logic is that we can often think of proportions of 0 or 1 as being qualitatively different and generated through a different process as the other proportions.

Language: Stata
Requires: Stata version 8.2
