Robust estimation of lognormal distribution parameters.
lognormRob(x, estim = c("tdmean"), control = lognormRob.control(estim, ...), ...)a list with class “fitdstn” containing the following elements:
a named numeric vector containing the parameter estimates.
a named numeric vector containing the standard deviations of the parameter estimates. Missing in current implementation.
a numeric matrix containing the variance-covariance matrix of the estimated parameter vector. Missing in current implementation.
a single numeric value containing an estimate of the mean.
a single numeric value containing the variance of the estimated mean.
a list containing the control parameters used by the estimator.
a numeric vector containing the sample.
a character string specifying which estimator to use.
a list of control parameters appropriate for the estimator in estim.
control parameters may also be given here.
