Suppose that we have a statistical model with parameter space . A null hypothesis is often stated by saying that the parameter is in a specified subset of . The alternative hypothesis is thus that is in the complement of , i.e. in , which is denoted by . The likelihood ratio test statistic for the null hypothesis is given by: where the quantity inside the brackets is called the likelihood ratio.

WebA likelihood ratio of 1.0 indicates that there is no difference in the probability of the particular test result (positive result for LR+ and negative result for LR−) between those with and without the disease. WebSince the positive class likelihood ratio is much larger than 1.0, it means that the machine learning-based diagnosis tool is useful: the post-test odds that the condition is truly present given a positive test result are more than 12 times larger than the pre-test odds.
