qemp: Empirical quantile function

In skewsamp: Estimate Sample Sizes for Group Comparisons with Skewed Distributions

Description

Empirical quantile function, i.e. inverse of the empirical cumulative density function pemp(). Based on the latter function as presented by Chakraborti (2006).

Usage

qemp(p, sample)

Arguments

p	probability, can be a vector
sample	numeric vector of sample values to base the ECDF on

Value

Returns the value for which pemp(x, sample) = p, i.e. the probability that a value drawn at random from the ECDF is smaller or equal to x is p.
