IntCount: a Stata command for estimating count data models from interval data


Publication date

10 Oct 2018


This article describes a user-written Stata command, intcount, for estimation of a number of regression models for count data which are observed in interval form. The models available are Poisson, negative binomial and binomial, and they can be estimated in standard or zero-inflated form. Use of the command is illustrated with an application to analysis of data from the UK Understanding Society survey on the demand for healthcare services.
