Normalization by a pooled sample from group
WebThe assumptions on the means are the same as that of the ANOVA; that is, they are assumed to be from normally distributed populations with common variance . The grand mean is , and the pooled estimate of the common but unknown variance is. Note that the pooled estimate of the variance is identical to MSW in the ANOVA.
