Correctness of Kruskal's Algorithms for Monotone Regression with Ties
de Leeuw, Jan
Psychometrika, 42, 1, 141-4, Mar 77
Kruskal has proposed two modifications of monotone regression that can be applied if there are ties in nonmetric scaling data. In this note Kruskal's conjecture that his algorithms give the optimal least squares solution of these modified monotone regression problems is proven. Also, an additional approach is proposed.
