WebAs with other ANOVA methods, assumption of normality of the response measurements and variance homogeneity among groups are considered to be satisfied. In addition, the univariate ANOVA requires that each pair of repeated measures has the same correlations, this feature is known as ‘compound symmetry’. Web22 de nov. de 2024 · Just like Skewness, Kurtosis is a moment based measure and, it is a central, standardized moment. Because it is the fourth moment, Kurtosis is always positive. Kurtosis is sensitive to departures from normality on the tails. Because of the 4th power, smaller values of centralized values (y_i-µ) in the above equation are greatly de …
