RE: [R] Jonckheere-Terpstra test

2003-10-06 Thread Kim Mouridsen
The Jonckheere-Terpstra test is a distribution-free test for ordered alternatives in a one-way layout. More specifically, assume X_ij = m + t_j + e_ij, i=1,...,n_j and j=1,...,k, where the errors are idependent and identically distributed. Then you can use the Jonckheere-Terpstra to

Dear R-users I'm considering a repeated measures experiment where two within-subject factors A (2 levels) and B (3 levels) have been measured for each of 14 subjects, S. I wish to test the effect of factor A. I know that a variance component model with random effects S, S:A, S:B and S:A:B can be
