Contindic {GB2}

Sensitivity Analysis of Laeken Indicators on GB2 Parameters

Description

Produces a contour plot of an indicator for a given shape1.

Usage

contindic.gb2(resol, shape1, shape21, shape22, shape31, shape32, fn, title, table=FALSE)

Arguments

resol

numeric; number of grid points horizontally and vertically.

shape1

numeric; positive parameter, first shape parameter of the GB2 distribution.

shape21, shape22, shape31, shape32

numeric; limits on the positive parameters of the Beta distribution.

fn

string; the name of the function to be used for the calculation of the values to be plotted.

title

string; title of the plot.

table

boolean; if TRUE, a table containing the values of the function fn at the different grid points is printed.

Details

An indicator is defined as a function of three parameters. The shape parameter, shape1, is held fixed. The shape parameters shape2 and shape3 vary between shape21 and shape22, and shape31 and shape32, respectively.

Value

A contour plot of a given indicator for a fixed value of the shape parameter shape1.
