In likelihood.model: Likelihood-Based Statistical Inference in the Fisherian Tradition

Likelihood ratio test

Description

Computes the likelihood ratio test statistic and p-value for nested models.

Usage

lrt(null, alt, data, null_par, alt_par, dof = NULL, ...)

Arguments

null	the likelihood model for the simpler (null) hypothesis nested within the alternative model
alt	the likelihood model for the more complicated (alternative) hypothesis
data	a data frame
null_par	parameter values under the null model
alt_par	parameter values under the alternative model
dof	degrees of freedom (computed automatically if NULL)
...	additional arguments passed to loglik

Value

An lrt_result object with components stat, p.value, and dof
