The Cressie-Read test for discrete data.
Description
Goodnes of fit test for two distributions: Poisson, binomial and negative binomial.
Usage
chi2.test(x, dist = "pois", lambda = 1)
Arguments
x
a numeric vector of values.
dist
names distributions: pois (deflaut), binom or nbinom
lambda
parameter lambda test Cressie-Read.
Value
An object of class "htest" containing the following components:
- estimate
estimates distribution parameters and loglik
- parameter
the degrees of freedom and lambda parameter
- statistic
statistic test value
- p.value
p-value
