Module Statsample::Bivariate provides covariance and pearson, spearman, point biserial, tau a, tau b, gamma, tetrachoric (see Bivariate::Tetrachoric) and polychoric (see Bivariate::Polychoric) correlations. Include methods to create correlation and covariance matrices ...
Calculating covariance is a step in the calculation of a correlation coefficient. A covariance matrix is the basis of a correlation matrix. Normally correlation coefficients are preferred due to their standardized measure which makes it easy to compare covariances across many differently scaled variables...

Example 2: What sample size would be required to detect a partial eta-square effect size of .2 for the interaction between the two factors with power 95% if the experiment in Example 1 ofTwo-way MANOVA Exampleis to be repeated?
The covariance structure may take on several forms depending on the nature of the experiment and the subjects involved. This procedure allows you to calculate sample sizes using four different covariance patterns: Compound Symmetry, AR(1), Banded(1), and Simple. This procedure can be used to ...
