LR.test: 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

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

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.
