Quantlet: | ranpois | |
Description: | generates arrays (up to 8 dimensions) of pseudo random variables with Poisson distribution. |
Usage: | y = ranpois(n,lambda) | |
Input: | ||
n | m x 1 vector of positive integers, x_m is the number of elements in m-th dimension of the array (m <= 8) | |
lambda | scalar, parameter of the Poisson distribution (0 < lambda) | |
Output: | ||
y | x1 x ... x x_m array, random generated numbers with Poisson distribution |
