O'Brien's Test for Homogeneity of Variances.
In the Obrien's test to check out the homogeneity of variances the data are transforming to
yij = ((nj-1.5)*nj*((xij-mean(xj))**2)-((0.5)*(var(xj))*(nj-1)))/((nj-1)*(nj-2))
and uses the F distribution performing an one-way ANOVA using y as the dependent variable.
