bifit: Compute WLS using Tukey's biweight function

In mpascariu/MortalityEstimate: Indirect Estimation Methods for Measurement of Demographic Indicators

Description

Compute WLS using Tukey's biweight function

Usage

bifit(x, y, c, intercept, tol.biweight, tol.lsfit)

Arguments

x	A matrix whose rows correspond to cases and whose columns correspond to variables. x matrix should not include a column of ones
y	The responses, possibly a matrix if you want to fit multiple left hand sides. y can be matrix if there are multiple left-hand sides
c	Tuning constant when compute weighted least squared using Tukey's biweight function. Typically, between 6 to 9.
intercept	logical. Whether or not an intercept term should be used in least squares estimation. See lsfit.
tol.biweight	Tolerance for convergence of the biweight fit
tol.lsfit	Tolerance to be used in the matrix decomposition in least squares estimation. See lsfit.
