Who are Cochran and Armitage?
[edit]I assume Peter Armitage and William Gemmell Cochran are meant...
Clarification of the Genetics Example
[edit]You may want to add that standardized test statistic means T/sqrt(Var(T)) — Preceding unsigned comment added by 71.197.234.248 (talk) 03:46, 1 December 2011 (UTC)
Reference for Test Statistic?
[edit]The equation for the test statistic does not seem to match those in the referenced Agresti book or the original papers due to Cochran and Armitage. It only seems to match the reference from StatGen. While I assume that is a reputable group, it doesn't seem the best reference for a number of reasons. If anyone knows a better reference for the given equation, especially one that explains how it is equivalent to the more standard form, please add it. Polynumeric (talk) 23:08, 11 November 2021 (UTC)
