The paper suggests alternative methods where measures location replaced by robust effect size that is in part dispersion. used here does not assume the have common That is, it deals with heteroscedasticity.

In general, the coefficient estimates of linear models are carried out using ordinary least squares (OLS) method. Since analysis variance is also a model, coefficients can be estimated least-squares this study, in two-way were performed by Cholesky decomposition. The purpose decomposition finding make variables used model being orthogonal such that important easily identified. sum (row, column,...
