Using STATA for mixed-effects models (i

Mixed models consist of fixed effects and random effects. The fixed effects are specified as regression parameters . in a manner similar to most other Stata estimation commands, that is, as a dependent variable followed by a set of . regressors. The random-effects portion of the model is specified by first considering the grouping structure of ...

Count outcomes - Poisson regression (Chapter 6)

• The Poisson is different than the binomial, Bin(n, π), which takes on numbers only up to some n, and leads to a proportion (out of n). • But the Poisson is similar to the binomial in that it can be show that the Poisson is the limiting distribution of a Binomial for large n and small π.
