Permutation Test on Interactions {coin}
...this in the package documentation (or
anywhere else), I'm not sure how to specify the test in this case. For
example, should I interpret the p-value in the example below as the pvalue
of the interaction effect between group and the covariate x.
set.seed(1)
library("coin")
data("rotarod", package = "coin")
x <- rnorm(24)
rotarod <- cbind(rotarod, x)
pvalue(independence_test(time ~ group * x, data = rotarod))
Your advice would be much appreciated.
Regards,
Axel.
