What is the desired confidence level for the interval?
(for example, 95 for 95% confidence)


What is the sample size, n?


What is the quantile? (for example, .05 for the 5th percentile)





This page is a form for determining the order statistic that corresponds to a one-sided, lower, nonparametric confidence bound on a quantile of a distribution. Here is FORTRAN source code for a standalone program that yields the order statistic that corresponds to a one-sided, lower, nonparametric confidence bound on a quantile.

The theory behind this program is briefly discussed in:
