Likelihood Ratio Test for SECR Models

Description

Compute likelihood ratio test to compare two fitted models, one nested within the other.

Usage

LR.test(secr1, secr2)

Arguments

secr1 fitted secr model
secr2 fitted secr model

Details

The test statistic is twice the difference of the maximized likelihoods. It is compared to a chi-square distribution with df equal to the number of extra parameters in the more complex model.

The models must be nested (no check is performed - this is up to the user), but either secr1 or secr2 may be the more general model.

Value

Object of class 'htest', a list with components

statistic value the test statistic
parameter degrees of freedom of the approximate chi-squared distribution of the test statistic
p.value probability of test statistic assuming chi-square distribution
method character string indicating the type of test performed
data.name character string with names of secr models compared
