gammaRob: Robust Estimation of Gamma Distribution Parameters

In robust: Port of the S+ "Robust Library"

Robust Estimation of Gamma Distribution Parameters

Description

Robust estimation of gamma distribution parameters

Usage

gammaRob(x, estim = c("M", "tdmean"), control = gammaRob.control(estim, ...), ...)

Arguments

x	a numeric vector containing the sample.
estim	a character string specifying which estimator to use.
control	a list of control parameters appropriate for the estimator in estim.
...	control parameters may also be given here.

Value

a list with class “fitdstn” containing the following elements:

estimate	a named numeric vector containing the parameter estimates.
sd	a named numeric vector containing the standard deviations of the parameter estimates.
vcov	a numeric matrix containing the variance-covariance matrix of the estimated parameter vector.
mu	a single numeric value containing an estimate of the mean.
V.mu	a single numeric value containing the variance of the estimated mean.
control	a list containing the control parameters used by the estimator.

The print method displays the estimated parameters and their standard errors (in parentheses).
