CPP.Tri.Choquet {CPP}

CPP for sorting alternatives, based on Choquet integrals

Description

This function computes the CPP-Tri with Choquet integrals, using Beta PERT distributions to randomize the decision matrix. The CPP Tri is used to classify alternatives, indicating the order of a number of classes defined by the decision maker. The probabilities of each alternative being higher and lower than the classes' profiles are composed by Choquet integrals.

Usage

CPP.Tri.Choquet(x, q, s)

Arguments

x

Decision matrix of Alternatives (rows) and Criteria (columns). Benefit criteria must be positive and cost criteria negative.

q

Vector of quantiles, indicating the classes' profiles.

s

Shape of a Beta PERT distribution, as described in the package 'mc2d'. There is no default value, however the higher the shape the higher the kurtosis, which emulates the precision of data.

Value

Choquet.O returns the probabilities of each alternative being higher than the classes' profiles, composed by Choquet integrals. Choquet.U indicates the probabilities of each alternative being lower than the classes' profiles. CPP.Tri.Chq returns the alternatives' classes.
