S. Hashem et B. Schmeiser, ALGORITHM 727 - QUANTILE ESTIMATION USING OVERLAPPING BATCH STATISTICS, ACM transactions on mathematical software, 20(1), 1994, pp. 100-102
An efficient algorithm for estimating the qth quantile of a set of n d
ata points is introduced. The standard error of the quantile estimate
is estimated using overlapping batch statistics. A driver program is i
ncluded.
