rht.control: Control function for rht

In rhte: Robust Horvitz-Thompson Estimation

Description

This function specifies the parameters needed to compute robust estimators

Usage

rht.control(acc = 1e-06, steps = 50, asymmetric = FALSE, 
            quietly = FALSE, exact = FALSE, ddigits = 3, ...)

Arguments

acc	scalar; determines the precision in the termination rule of the IRWLS algorithm
steps	scalar (integer); determines the maximal number of IRWLS iterations
asymmetric	logical; FALSE gives symmetric (standard) Huber psi-function (default); TRUE gives the asymmetric Huber psi-function
quietly	logical; default is FALSE; if quietly is TRUE, the text/message output (stdout) of all algorithms is suppressed (this is useful in simulation studies)
exact	locial; if TRUE the exact asymptotic variance of the M-estimator is computed, where exact means that the variance of the scale estimate is considered; if FALSE, the contribution of the scale variance is neglected (default).
ddigits	scalar (integer); determines the number of relevant decimal digits to be reported (default=3)
...	additional specifications

Details

The user may specify parameters differently if needed. Notably, if the algorithm fails to converge, one may consider modifying the number of iterations (steps) and/or the precision (acc).

Value

A list consisting of the parameter values.
