Binary hypothesis testing
WebBy testing for di erences in the gene expression levels we can detect/classify di erent types of disease. 2 The Likelihood Ratio Test Assume that we observe a random variable distributed according to one of two distributions. H 0: X ˘ p 0 H 1: X ˘ p 1 Deciding which of the two best ts an observation of X is called a simple binary hypothesis ... WebMar 31, 2024 · $\begingroup$ The t-test answers the hypothesis test. The effect size is a measure of practical significance. The effect size is a measure of practical significance. Associated with t-tests, there are often two effect sizes that are reported to supplement the t-test's assessment of statistical significance. $\endgroup$
