Nonparametric scaling: a descriptive index.
A descriptive index (CI) based on the U statistic is presented. The CI permits to quantify the differences between experimental samples taking into account both the location and variability features of the data without any distributional assumption. This index can be useful to build activity scales for series of compounds.
