simpln {degreenet}

Simulate from a Poisson Lognormal Distribution

Description

Functions to generate random samples from a Poisson Lognormal Probability Distribution

Usage

simpln(n=100, v=c(0.6,1.2), maxdeg=10000, cutoff=1)

Arguments

n

number of samples to draw.

v

Poisson Lognormal parameters: lognormal mean and lognormal s.d.

maxdeg

Maximum degree to sample (using truncation of the distribution).

cutoff

Calculate estimates conditional on exceeding this value.

Value

vector of random draws or samples.

Note

See the papers on https://handcock.github.io/?q=Holland for details
