EVPlot: Extreme value plot (frequency and growth curves)
Description
Plots the extreme value frequency curve or growth curve with observed sample points. With the option of generalised extreme value (GEV), generalised Pareto (GenPareto), or generalised logistic (GenLog) distributions.
Usage
EVPlot(
x,
dist = "GenLog",
scaled = TRUE,
Title = "Extreme value plot",
ylabel = NULL
)
Arguments
x
a numeric vector. The sample of interest
dist
a choice of distribution. "GEV", "GenLog", or "GenPareto". The default is "GenLog"
scaled
logical argument with a default of TRUE. If TRUE the plot is a growth curve (scaled by the QMED). If FALSE, the plot is a frequency curve
Title
a character string. The user chosen plot title. The default is "Extreme value plot"
ylabel
a character string. The user chosen label for the y axis. The default is "Q/QMED" if scaled = TRUE and "Discharge (m3/s)" if scaled = FALSE
