Mises family (equation (14)) with the weighting function of the form F = 1 for complete
samples, and x = 1 for left-truncated samples, that gives a higher weight to the upper
tail and a lower weight to the lower tail. We define this statistic as AD.
Let X be the vector of the order statistics, such that X(1) ≤ X(2) ≤ ... ≤ X(n). Its general
form for complete samples can be expressed as:
