Get the Constant for Consistency for the M-Scale and for Efficiency for the M-estimate of Location

Returns the tuning constants required to achieve the desired breakdown point or efficiency under the Normal model.

Usage

consistency_const(delta, rho, eps = sqrt(.Machine$double.eps))

efficiency_const(eff, rho, eps = sqrt(.Machine$double.eps))

Arguments

delta

desired breakdown point (between 0 and 0.5)

rho

the name of the chosen \(\rho\) function. See rho_function() for a list of supported functions.

eps

numerical tolerance level for equality comparisons

eff

desired asymptotic efficiency (between 0.1 and 0.99).

Value

consistency constant
