WebChapter 17 Poisson-lognormal GLMM. A second option for a distribution where the variance increases more rapidly with the mean is the Poisson-lognormal distribution. This model effectively places a lognormal prior on \(εi\).. A Poisson-lognormal distribution with mean \(µ\) and lognormal prior variance \(σ2\) has variance: \(var(y) = µ + µ2 [exp(σ2) - 1]\) WebNov 5, 2024 · But as it is written here: The central limit theorem says that the distribution of the mean of N draws from a probability distribution approaches a Gaussian of width σ N …
