# Is there a non-parametric test, like a Kruskal-Wallis, but with uneven blocks?

I have a continuous response variable, nominal independent, and want to block by site, though the numbers at sites are unequal. Is there any alternative to a permutation test? If not, does anyone know of an automated process for designing a permutation test for a rookie like me?

Thanks very much

Isn't a "response variable" the same as a "dependent" (variable)? How, then, can it be at once "continuous" and "discrete"? –  whuber Oct 21 '11 at 15:14

The proportional odds ordinal logistic model is a generalization of the Kruskal-Wallis and Wilcoxon 2-sample tests that can handle many different setups including covariate adjustment.
