## Poisson lognormal and bivariate Poisson lognormal distribution

### Description

Functions for obtaining the density, random deviates and maximum likelihood estimates of the Poisson lognormal distribution and the bivariate Poisson lognormal distribution.

### Details

`dpoilog` returns the density, `rpoilog` returns random deviates and `poilogMLE` performs maximum likelihood estimation of parameters for the Poisson lognormal distribution.

`dbipoilog` returns the density, `rbipoilog` returns random deviates and `bipoilogMLE` performs maximum likelihood estimation of parameters for the bivariate Poisson lognormal distribution.
