The supremum class Anderson-Darling test compares the null distribution with the empirical distribution of the observed data. The test statistic is given by
AD+ = sqrt(n) sup((zH + j/n (1-zH) -zj)/sqrt((zj-zH)(1-zj))
AD+ = sqrt(n) sup(zj - (zH + (j-1)/n (1-zH)))/sqrt((zj-zH)(1-zj))
AD = max(AD+, AD-).
with z_H = F_theta(H) and z_j=F_theta(x_j), where x_1, …, x_n are the ordered data values. Here, F_theta is the null distribution.
