L-moments {RFA}R Documentation

Generate several L-moments plots

Description

Produces several plot given the first 3 sample L-moments ratio.

Usage

lmomplots(lmom.reg, which = 1:3, ask = nb.fig < length(which) &&
dev.interactive(), pch = 15, draw.dist = TRUE)

Arguments

lmom.reg A list. Typically, it is the result of function lmomreg.
which A numeric vector which specifies which L-moments plot should be plotted. '1' for L-Skewness - L-CV, '2' for L-Kurtosis - L-CV and '3' for L-Skewness - L-Kurtosis plot. By default, the 3 plots are produced.
ask Logical. If TRUE user is asked before a new plot is drawn.
pch Numeric. Specifies the symbol to use for the 'regional point'. See points.
draw.dist Logical. If set to TRUE - the default, then theoretical lines of some distribution are displayed in the L-Skewness / L-Kurtosis space.

Details

For the L-Skewness / L-Kurtosis plot, theoretical lines of Generalized Logistic, Generalized Extreme Value, Generalized Pareto, Log-Normal a,d Pearson Type III are displayed. OLB is the overall lower bound of tau_4 as a function of tau_3. The triangles U, N, G and E correspond respectively to the Uniform, Normal, Gumbel and Exponential cases.

Value

Produces several plots.
