Permutation Tests in R!

“ There are many situations were parametric linear model significance tests are not optimal (including when data is notably non-normal, there are outliers, and when sample sizes are too small to trust asymptotic results). In these cases, permuation tests may be viable alternatives.” lmPerm package provides permutation tests for linear models in R. It can be used for ANOVA, ANCOVA, polynomial regression, and multiple regression.
