The quantity actually tested: Pr ^(X1<X2)+ Pr ^(X1=X2)/2 is then described and recommended as the basis for an alternative summary statistic that can be employed instead of medians. In order to graphically represent an estimate of the quantity: Pr(X1 < X2) + Pr(X1 = X2)/2, use of a… Continue Reading →
