hl.loc: Hodges - Lehmann Estimator of Location

Description

Function to compute the Hodges - Lehmann estimator of location in the one sample case.

Usage

hl.loc(x, na.action = na.fail)

Arguments

x

a numeric vector.

na.action

a function which indicates what should happen when the data contain 'NA's. Default is to fail.

Value

the Hodges - Lehmann estimator of location.

Details

The Hodges - Lehmann estimator is the median of the combined data points and Walsh averages. It is the same as the Pseudo Median returned as a by-product of the function wilcox.test.
