Robust Fitting of Univariate Distributions

Description

Robust Fitting of Univariate Distributions.

Usage

fitdstnRob(x, densfun, ...)

Arguments

x	A numeric vector containing the sample.
densfun	a character string naming the distribution. Distributions ‘gamma’, ‘lognormal’, and ‘weibull’ are recognized.
...	additional arguments are passed to the fitting functions.

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.
call	the matched call.
densfun	the character string densfun provided in the arguments.
x	the data provided in x.

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