CPP.Axes.Normal {CPP} | R Documentation |
This function computes the CPP by axes, using Normal distributions to randomize the decision matrix. The CPP by axes is used to rank alternatives in multicriteria decision problems. The "Progressive-Conservative" and the "Optimist-Pessimist" axes emulate four decision maker's points of view.
CPP.Axes.Normal(x)
x |
Decision matrix of Alternatives (rows) and Criteria (columns). Benefit criteria must be positive and cost criteria must be negative. |
PMax are the joint probabilities of each alternative being higher than the others, per criterion. PMin are the joint probabilities of each alternative being lower than the others, also by criterion. Axes returns the alternatives' scores by axis and ranking for decisionmaking.
