FuzzyStatTra (version 1.0)

HyperI:

Description

This function calculates the hyperbolic inequality index for a sample of trapezoidal positive fuzzy numbers contained in a matrix F. The function first checks if the input matrix F is given in the correct form (tested by checkingTra).

Usage

HyperI(F, c = 0)

Arguments

F

matrix of dimension n x 4 containing n trapezoidal positive fuzzy numbers characterized by their four values inf0,inf1,sup1,sup0. The function implicitly checks if the matrix is in the correct form (tested by checkingTra).

c

number in [0,0.5]. The c*100% trimmed mean will be used in the calculation of the hyperbolic inequality index.

Value

The function returns the hyperbolic inequality index, which is a real number.
