Two-sample likelihood ratio test
WebA likelihood ratio test is one way of obtaining a test -- more specifically, it defines a way to obtain a test statistic (and consequently, to obtain a rejection rule), based on the ratio of two likelihoods. LRTs have some attractive properties. WebNov 29, 2024 · A likelihood ratio test compares the goodness of fit of two nested regression models. A nested model is simply one that contains a subset of the predictor variables in the overall regression model. For example, suppose we have the following regression model with four predictor variables: Y = β 0 + β 1 x 1 + β 2 x 2 + β 3 x 3 + β 4 x 4 + ε
