“For continuous data, it [the common language statistic] is the probability that a score sampled at random from one distribution will be greater than a score sampled from some other distribution.” (McGraw and Wong, 1992)
This function calculates the fraction of all possible pairings between x
and y
where the difference (y - x) is positive.

# generate synthetic data for heights in inches of 18-24 # year-old males and females (NCHS, 1987, Tables 13 and 14) height_male <- rnorm(988, 69.7, 2.8) height_female <- rnorm(1066, 64.3, 2.6) # the CLES is approximately 0.92 (McGraw and Wong, 1992) CLES(height_female, height_male)
