hbrwts_gr {rlme}

HBR Weight

Description

Calculates hbr weights for the GEER method. This turns a vector of weights for a vector of errors. Used to make factor space more robust, up to 50% breakdown. See HM (2012) and Terpstra and McKean (2005) for details. The ww package produces this weights as well.

Usage

hbrwts_gr(xmat, y, percent = 0.95, intest = ltsreg(xmat, y)$coef)

Arguments

xmat

Design matrix, pxn, without intercept.

y

Response vector in nx1.

percent

This is 0.95.

intest

This is obtained from myltsreg(xmat, y)$coef

Details

The ww package explains how it is obtained.
