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...
ppmlhdfeis a Stata package that implements Poisson pseudo-maximum likelihood regressions (PPML) with multi-way fixed effects, as described inCorreia, Guimarães, Zylkin (2019a). The estimator employed is robust to statistical separation and convergence issues, due to the procedures developed inCorr...

By construction, the pseudo−R2 is between zero and one, and increases toward one as variables are added to a model. Beyond that, it is difficult to extend the analogy to the R2 in a linear model, since the maximum likelihood estimation (MLE) in the Poisson model is not computed so ...

where wij are independent standard normal pseudo-random numbers and ρ is specified such that the correlation between any two variables is given by ρ2. Four different sets of correlations are investigated corresponding to ρ=0.85,0.9,0.99 and 0.999. Number of explanatory variables is determined as...
Parameter estimation Maximum likelihood Given a sample of n measured values k we wish to estimate the value of the parameter λ of the Poisson population from i which the sample was drawn. The maximum likelihood estimate is[citation needed] Since each observation has expectation λ so does this...
