WebFeb 13, 2024 · To determine the p-value, you need to know the distribution of your test statistic under the assumption that the null hypothesis is true.Then, with the help of the cumulative distribution function (cdf) of this distribution, we can express the probability of the test statistics being at least as extreme as its value x for the sample:Left-tailed test: p … WebF–test checks poolability in an otherwise perfect Gauss-Markov regression with E ′ = ˙2 I. To cope with this problem, one may also test for i = and/or t = in a (one-way or two-way) RE model. This test is called the Roy-Zellner test. Essentially, it tests for ‘fixed-type’ poolability of slope coefficients in a random-effects model.
