A test for overall significance of regression analysis. The p-value from F-score is given by the following formulae, where we let cdfF,d1,d2 denote the cumulative distribution function of the F-distribution, with (d1, d2)-degrees of freedom: Left-tailed F-test: Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Then, with 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: Two-tailed test: p-value = 2 * min{cdf(x) , 1 - cdf(x)}, If the distribution of the test statistic under H0 is symmetric about 0, then a two-sided p-value can be simplified to p-value = 2 * cdf(-|x|), or, equivalently, as p-value = 2 - 2 * cdf(|x|).
