Robust Estimation of Lognormal Distribution Parameters
Description
Robust estimation of lognormal distribution parameters.
Usage
lognormRob(x, estim = c("tdmean"), control = lognormRob.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 |
... |
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. Missing in current implementation. |
vcov |
a numeric matrix containing the variance-covariance matrix of the estimated parameter vector. Missing in current implementation. |
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. |
Note
The print method displays the estimated parameters and their
standard errors (in parentheses).
