fit_dist_pois {ABCp2}

Fit Offspring Distribution to the Poisson Distribution

Description

This function fits offspring data to the Poisson distribution, and tests the goodness of fit using the chi-squared test.

Usage

fit_dist_pois(dist)

Arguments

dist

a numeric vector of data values for number of offspring per dam.

Value

estimate

Lambda parameter estimated from the supplied distribution.

sd

Standard deviation of the lambda estimate.

vcov

Variance/covariance matrix of the lambda estimate.

loglik

the log-likelihood of the lambda estimate.

n

The number of observations.

statistic

The chi-squared test statistic.

parameter

Degrees of freedom for the chi-squared test.

p.value

P-value for the chi-squared test.

data_pois

Vector of values generated from the Poisson distribution.
