Compute MCDA weights

Given a square reciprocal-symmetric ratio matrix from an Analytic Hierarchy Process, calculate the vector of weights using the using the Pairwise Comparison Method (Saaty 1987, Saaty 1996, Malczewski 1999)

compute_weights(x)

Arguments

x

matrix of pair-wise assessment of relative importance of risk factors.

Value

numeric vector of weights
