In kciomek/rorutadis: Robust Ordinal Regression UTADIS

Description

This function calculates possible and necessary assignments.

Usage

calculateAssignments(problem, necessary)

Arguments

problem	Problem for which assignments will be calculated.
necessary	Whether necessary or possible assignments.

Value

n x p logical matrix, where each row represents one of n alternatives and each column represents one of p classes. Element [i, h] is TRUE if:

• for necessary assignments: alternative a_i is always assigned to class C_h,

• for possible assignments: alternative a_i can be assigned to class C_h.

Examples

perf <- matrix(c(5, 2, 1, 7, 0.5, 0.9, 0.4, 0.4), ncol = 2)
problem <- buildProblem(perf, 3, FALSE, c('g', 'g'), c(0, 0))
problem <- addAssignmentsLB(problem, c(1, 2), c(2, 3))

possibleAssignments <- calculateAssignments(problem, FALSE)
necessaryAssignments <- calculateAssignments(problem, TRUE)
