\title{Non-stationary GEV Parameter Estimation}
\usage{
nsgev(xdat, ntry = 20, ftol = 1e-06)
}
\arguments{
\item{xdat}{A numeric vector of data to be fitted (e.g., annual maximum values).}

\item{ntry}{Number of attempts for optimization (default 20).}

\item{ftol}{Function tolerance for optimization (default 1e-6).}
}
\value{
A list containing:
\itemize{
  \item \code{para.prop} - The proposed L-moment based estimates
        (mu0, mu1, sigma0, sigma1, xi).
  \item \code{precis} - Precision of the optimization.
}
}
\description{
Estimates parameters of a non-stationary Generalized Extreme Value (GEV)
distribution using the L-moment-based algorithm from Shin et al. (2025,
J. Korean Stat. Soc.).

This is a convenience wrapper around \code{\link{lme.gev11}}, providing
compatibility with the original nsgev package interface (and with
GLmom v1.x).

\examples{
data(PhliuAgromet)
result <- nsgev(PhliuAgromet$prec, ntry = 5)
print(result$para.prop)
