Term: Likelihood Ratio Test (LRT)
Last Updated: 2007-10-20
As the name implies, the likelihood ratio is a ratio of two likelihoods. It is widely used as a test statistic, perhaps especially for relations among categorical variables displayed in contingency tables. The smaller the LR, the stronger the relationship. This is because (in comparison with the chi-square method) with the LR we attempt to accept a particular model, not reject a null hypothesis.
