In bivpois: Bivariate Poisson Distribution

Random values generation from the bivariate Poisson distribution

Description

Random values generation from the bivariate Poisson distribution.

Usage

rbp(n, lambda)

Arguments

n	The sample size.
lambda	A vector with the three parameters, (\lambda_1,\lambda_2,\lambda_3) of the Poisson distribution.

Details

In order to generate values from this distribution one needs three independent Poisson variables, X_1 \sim \text{Po}\left(\lambda_1\right), X_2 \sim \text{Po}\left(\lambda_2\right) and X_3 \sim \text{Po}\left(\lambda_3\right). Then, \left(X,Y\right)=\left(X_1+X3,X_2+X_3\right) \sim \text{BP}\left(\lambda_1,\lambda_2,\lambda_3\right).

Value

A matrix with n rows and 2 columns.
