poissonsim: Simple Poisson Regression Data Simulator

Description

This function simulates simple regression data from a Poisson model. It also has the option to create over-dispersed data of a particular type.

Usage

poissonsim(x = seq(0, 1, length=101), a = 2, b = -4, intcp.sd=NULL, slope.sd=NULL, seed=NULL)

Arguments

x

a numeric vector representing the explanatory variable

a

the regression function intercept

b

the regression function slope

intcp.sd

standard deviation of the (random) intercept

slope.sd

standard deviation of the (random) slope

seed

numeric constant

Value

• a list consisting of
• x
  the explanatory variable vector
• y
  the Poisson response vector
