lmomwei {lmomco} | R Documentation |
This function estimates the L-moments of the Weibull distribution given the parameters
(zeta, β, and delta) from parwei
. The Weibull distribution is a reverse Generalized Extreme Value distribution. As result, the Generalized Extreme Value algorithms (lmomgev
) are used for computation of the L-moments of the Weibull in this package (see parwei
).
