weighted_IQR: Weighted Interquartile Range (IQR)

In robsurvey: Robust Survey Statistics Estimation

Weighted Interquartile Range (IQR)

Description

Weighted (normalized) interquartile range

Usage

weighted_IQR(x, w, na.rm = FALSE, constant = 0.7413)

Arguments

x	[numeric vector] data.
w	[numeric vector] weights (same length as x).
na.rm	[logical] indicating whether NA values should be removed before the computation proceeds (default: FALSE).
constant	[double] constant scaling factor to make the weighted IQR a consistent estimator of the scale (default: 0.7413).

Details

By default, the weighted IQR is normalized to be an unbiased estimate of scale at the Gaussian core model. If normalization is not wanted, put constant = 1.

Value

Weighted IQR
