Installation

$ npm install johnsons-relative-weights

Usage

const jrwAnalysis = require('johnsons-relative-weights');

const jrwResults = jrwAnalysis(
    [
        [1.00, 0.66, 0.67, 0.54, 0.68, 0.62, 0.72],
        [0.66, 1.00, 0.58, 0.59, 0.68, 0.68, 0.56],
        [0.67, 0.58, 1.00, 0.52, 0.60, 0.62, 0.68],
