evquantile: Estimating populations quantiles of extreme values

Description

Computes population quantiles for given return periods. Estimation is done using L-moments.

Usage

evquantile(fit, return.period = NULL)

Value

A matrix containing the low-flow quantiles, with rows corresponding to return periods columns to distributions.

Arguments

fit

object of class evfit, possibly created with evfit().

return.period

numeric vector of return periods

Details

This function is vectorized over return.period.

Examples

data("ngaruroro")

# using tyears is a fast way to produce an object of class evfit
y <- tyears(ngaruroro, dist = "wei", event = 100, plot = TRUE)

# computing quantiles for given return periods
rp <- c(1.42, 5, 10)
evquantile(y, return.period = rp)
rpline(y, return.period = rp, suffix = c("a", "m\u00B3"))
