Regions of Pearson Distribution Types

Description

2D-Plot of the regions for the different types of Pearson distributions, depending on (squared) skewness and kurtosis.

Usage

pearsonDiagram(max.skewness = sqrt(14), max.kurtosis = 24, 
               squared.skewness = TRUE, lwd = 2, legend = TRUE, 
               n = 301)

Arguments

max.skewness

maximal value for the skewness.

max.kurtosis

maximal value for the kurtosis (not excess kurtosis!).

squared.skewness

plot squared skewness on x-axis (default: TRUE)?

lwd

line width for distributions of type II, III, V, VII.

legend

include legend in the plot (default: TRUE)?

n

number of points for curve.

Details

The label of the x-axis is \beta_1 for squared skewness and \sqrt{\beta_1} for regular skewness. The label of the y-axis is \beta_2.

Value

Nothing useful. Function called for its side-effects.
