| Tiivistelmä: | Various research areas face the methodological problems presented by nonnegative integer count data drawn from heterogeneous populations. The authors present a disaggregate negative binominal regression procedure for analysis of count data observed for a heterogeneous sample of cross-sections, possibly over some fixed time periods. This procedure simultaneously pools or groups cross-sections while estimating a separate negative binominal regression model for each group. |
