This function estimates the L-moments of the Weibull distribution given the parameters
(\(\zeta\), \(\beta\), 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).
Usage
lmomwei(para)
Value
An R
list is returned.
lambdas
Vector of the L-moments. First element is
\(\lambda_1\), second element is \(\lambda_2\), and so on.
ratios
Vector of the L-moment ratios. Second element is
\(\tau\), third element is \(\tau_3\) and so on.
trim
Level of symmetrical trimming used in the computation, which is 0.
leftrim
Level of left-tail trimming used in the computation, which is NULL.
rightrim
Level of right-tail trimming used in the computation, which is NULL.
source
An attribute identifying the computational
source of the L-moments: “lmomwei”.
Arguments
para
The parameters of the distribution.
