In QuantileNPCI: Nonparametric Confidence Intervals for Quantiles

Description

Calculate nonparametric confidence intervals for quantiles using fractional order statistics,

Usage

quantCI(x, q, alpha, method)

Arguments

x	vector of data
q	the quantile
alpha	the significance level
method	the method used for calculate the confidence interval. Options are "exact" or "approximate".

Value

returns a list of 5 values:

u1	the lower confidence limit of the quantile
u2	the upper confidence limit of the quantile
lower.ci	the estimated x value at u1
qx	the estimate x value of at the quantile q
upper.ci	the estimated x value at u2
