Description

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

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.
