The simplest, the Poisson regression model, is likely to be misleading unless restrictive assumptions are met because individual counts are usually more variable ("overdispersed") than is implied by the model. This model can be modified in 2 ways to accomodate this problem. In the overdispersed...
Poisson regression is different from linear en logistic regression, because it uses a log transformed dependent variable. For rates, defined as numbers of events per person per time unit, Poisson regression is very sensitive and probably better than standard regression methods....
poisson — Poisson regression Description Options References Quick start Remarks and examples Also see Menu Stored results Syntax Methods and formulas Description poisson fits a Poisson regression of depvar on indepvars, where depvar is a nonnegative count vari- able. If you have panel data, see ...

For scenarios in which are slightly more complicated, such as treated/control have different number of periods, you can use weights to get the same estimates. Here for example we have 25 periods in treated and 19 periods in the control using the regression approach. # Micro observations, diffe...
The study analysed data from the Malawi Demographic and Health Surveys (MDHSs) conducted in 2004, 2010, and 2015-16. The data included information about women aged 15 to 49 years and their education levels and fertility rates. The study used a regression method to measure the impact of outli...

This paper holds particular importance in identifying spatial clusters using a Geographically Weighted Regression (GWR) to model the risk of water damage in home insurance and improve the ratemaking process. A GWR is a statistical technique used to model non-stationary spatial relationships, meaning re...

A simple technique in the context of the methods discussed here is to use a random effects Poisson regression model, i.e. including a random intercept. The random intercept assumption is sensible since we expect individuals that already had an event to be at increased risk of having recurrence...
