WebThe Bayesian factor, the so-called likelihood ratio, has not always been well-understood. In this article, we try to discuss the likelihood ratio and its value for a specific test result, a positive or negative test result, and a range of test results, along with their graphical representations. Web6 de mar. de 2024 · MyHPV CHIP™ high-risk infection and cytology (LSIL or worse) showed the best specificity (93%, 95% CI 86–98) and the highest positive likelihood ratio (9.09, 95% CI 4.00–20.65) for high-grade squamous lesion detection.

Now, in light of the basic idea of maximum likelihood estimation, one reasonable way to proceed is to treat the " likelihood function " \ (L (\theta)\) as a function of \ (\theta\), and find the value of \ (\theta\) that maximizes it. WebLikelihood ratios summarise the ability of a test to revise the prior probability of disease. They can be summarised by established fixed-effects and random-effects methods. Results: Likelihood ratios precisely describe both directions of test performance.
