A Nonparametric K-Sample Test for Equality of Slopes.
Penfield, Douglas A.; Koffler, Stephen L.
Educational and Psychological Measurement, v46 n3 p537-42 Aut 1986
The development of a nonparametric K-sample test for equality of slopes using Puri's generalized L statistic is presented. The test is recommended when the assumptions underlying the parametric model are violated. This procedure replaces original data with either ranks (for data with heavy tails) or normal scores (for data with light tails). (Author/JAZ)
