Variants are selected by conducting stepwise likelihood ratio tests. The superiority of the proposed method over two existing variant selection methods is demonstrated in a simulation study.

A confidence interval on a parameter can be constructed by inverting a Wald-based or a likelihood ratio-based test. The approximate % Wald confidence interval for a parameter is ...

One of the usual assumptions for the GLM procedure is that the underlying errors are all uncorrelated with homogeneous variances. You can test this assumption in PROC GLM by using the HOVTEST option ...

A clinically useful test for either would thus have to have a high positive likelihood ratio (> 10) and low negative likelihood ratio (< 0.10).40 Based on the results of our review, pulsatility index ...
