11. Estimation of post-test probability from pre-test probability and likelihood ratio goes as follows: 12. This is primarily done for the column ( condition ) ratios, yielding likelihood ratios in diagnostic testing. 13. There are several reasons to prefer the likelihood ratio test or the Lagrange multiplier to the Wald test: 14. The highest ordered interactions are no longer removed when the likelihood ratio chi-square statistic becomes significant. 15. The conversion from the log-likelihood ratio of two alternatives also takes the form of a logistic curve. 16. In practice, the likelihood ratio is often used directly to construct tests see Likelihood-ratio test. 17. Is it really correct that the use of likelihood ratios in diagnostic testing requires that the variable be dichotomous? 18. That gives a likelihood ratio of 0.1045, and so pointing towards " M " 2. 19. With the likelihood ratio positive of 7 for the blood test, the post-test odds is calculated as: 20. The tenability of each model can be tested statistically by using a likelihood ratio test or other indices of fit.
