ppml estimates Poisson regression by pseudo maximum likelihood. It differs from Stata's poisson command because it uses the method of Santos Silva and Tenreyro (Santos Silva, J.M.C. and Tenreyro, S., 2010, On the Existence of the Maximum Likelihood Estimates in Poisson Regression, Economics...
AuthorBill Sribney, StataCorp Question: The version 5 documentation indicates the goodness-of-fit chi-squared statistic reported with the results of Poisson regression is a test of the null hypothesis that the dependent variable is Poisson distributed. My question is why this statistic (and perhaps...

The maximum likelihood estimator (MLE) suffers from the instability problem in the presence of multicollinearity for a Poisson regression model (PRM). In this study, we propose a new estimator with some biasing parameters to estimate the regression coefficients for the PRM when there is multicollinea...
Differences in neonatal, infant, and under-five child mortality across sociodemographic factors were presented using the chi-square test. The associations between exposure to HAP and child mortality outcomes were investigated using both univariable and multilevel mixed-effects Poisson regression models. As...
