WebAn informal check for this is to compare the ratio of the two sample standard deviations. If the two are equal, the ratio would be 1, i.e. \(\frac{s_1}{s_2}=1\). However, since these are samples and therefore involve error, we cannot expect the ratio to be exactly 1. ... We calculated all but one when we conducted the hypothesis test. We only ... Webamined confidence interval estimation for cross-product ratios in r x c contingency tables. 5. For estimation of linear discriminant coefficients, in the standard specification of the discriminant problem the coefficients are known only up to a common scalar, so it is only their ratios that can be estimated exactly.
