11. It is important in multivariate statistics and likelihood-ratio tests . 12. The more prominent of the two is the sequential probability ratio test ( SPRT ). 13. In practice, the likelihood ratio is often used directly to construct tests see Likelihood-ratio test . 14. The Likelihood ratio test has better behavior for small sample sizes, so it is generally preferred. 15. This is called the " minimum ratio test " . can be used to make the determination. 16. I misunderstood the results of the ratio test ; when the limit is 1 then it tells you nothing. 17. Because the sequential probability ratio test only evaluates probabilities near the cutscore, cutscore-based item selection is more appropriate. 18. The assumptions of normal distribution of errors and lack-of-fit test is the likelihood-ratio test of this null hypothesis. 19. The radius of convergence is 1 / " e ", as may be seen by the ratio test . 20. There are several reasons to prefer the likelihood ratio test or the Lagrange multiplier to the Wald test:
