Robust Estimation of Gamma Distribution Parameters
Robust estimation of gamma distribution parameters
gammaRob(x, estim = c("M", "tdmean"), control = gammaRob.control(estim, ...), ...)
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 |
... |
control parameters may also be given here. |
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).
