eu.planets_project.pp.plato.sensitivity.RangCorrelationTest

This sensitivity analysis test is similar to the OrderChangeCountTest. It first determines the "normal" ordering of alternatives (which is best, which is worst etc.). After each iteration (after each modification to the importance factors) the order of alternatives is recalculated. The new ordering is than compared with the normal ordering using the Spearman's rank correlation coefficient. The correlation coefficient is 0 if the ordering hasn't changed. The coefficients of all iterations for each node are added together and then devided by the number of iteration (= compute the average correlation coefficient). If this value exceeds a certain threshold the node is considered sensitive (the weight modification produces "too strong changes" in the ordering of the alternatives). @author Jan Zarnikov
