evquantile {lfstat}

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)

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.

Value

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

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"))
