WebThe likelihood ratio test statistic for the null hypothesis is given by: [8] where the quantity inside the brackets is called the likelihood ratio. Here, the notation refers to the supremum. As all likelihoods are positive, and as the constrained maximum cannot exceed the unconstrained maximum, the likelihood ratio is bounded between zero and one. WebHowever, you can’t use R-squared to assess the precision, which ultimately leaves it unhelpful. To illustrate this, let’s go back to the BMI example.
