The pooled estimate of the parent variance is s 2 = { (m - 1) s12 + (n - 1) s22 } / ( m + n - 2) and the variance of x - y, being t ...

The probability, computed assuming that H0 is true, that the test statistics would take a value as extreme or more extreme than that actually observed is called the P −value of th ...

On Limiting The Use Of Bayes In Presenting forensic Evidence
... A 2010 UK Court of Appeal Ruling (known as “R v T”) asserted that Bayes theorem and likelihood ratios should not be used in evaluating forensic evidence, except for DNA and ‘possibly other areas where there is a firm statistical base’. The potential impact of this ruling is enormous and it has drawn ...
