In reyzaguirre/rhep: Raul Eyzaguirre's R code

Chi-square goodness of fit test for Poisson distribution

Description

This function performs a chi-square goodness of fit test for a Poisson distribution.

Usage

chisq.pois(x, f, lambda = NULL)

Arguments

x	The observed values
f	The observed counts.
lambda	Poisson parameter.

Details

If lambda is not specified, then it is estimated from the data. If there are categories with expected counts less than 5 or less than 1 a warning is shown.

Value

It returns a table with the contribution to the chi-square statistic for each category, the chi-square statistic, the degrees of freedom, and the p-value.

Examples

x <- 0:9
f <- c(6, 16, 48, 77, 72, 72, 46, 39, 15, 9)
