gev.mle: Generalized extreme value maximum likelihood estimates for various quantities of interest

Description

This function calls the fit.gev routine on the sample of block maxima and returns maximum likelihood estimates for all quantities of interest, including location, scale and shape parameters, quantiles and mean and quantiles of maxima of N blocks.

Usage

gev.mle(
  xdat,
  args = c("loc", "scale", "shape", "quant", "Nmean", "Nquant"),
  N,
  p,
  q
)

Value

named vector with maximum likelihood estimated parameter values for arguments args

Arguments

xdat

sample vector of maxima

args

vector of strings indicating which arguments to return the maximum likelihood values for.

N

size of block over which to take maxima. Required only for args Nmean and Nquant.

p

tail probability. Required only for arg quant.

q

level of quantile for maxima of N exceedances. Required only for args Nquant.

Examples

dat <- mev::rgev(n = 100, shape = 0.2)
gev.mle(xdat = dat, N = 100, p = 0.01, q = 0.5)
