Low negative likelihood ratio

WebThe Likelihood-Ratio test (sometimes called the likelihood-ratio chi-squared test) is a hypothesis test that helps you choose the “best” model between two nested models. “Nested models” means that one is a special case of the other. For example, you might want to find out which of the following models is the best fit: Web26 mei 2011 · Furthermore, significant likelihood ratio test indicates that for our data, the negative binomial regression model fits better than the Poisson model. In this model we mainly aim to explore the effect of the practice of academic inbreeding on scientific productivity as quantified by the h -index.
