permutation test for linear models with continuous covariates
Hi I was wondering if there is a permutation test available in R for linear
models with continuous dependent covariates. I want to do a test like the
one shown here.
bmi<-rnorm(100,25)
x<-c(rep(0,75),rep(1,25))
y<-rnorm(100)+bmi^(1/2)+rnorm(100,2)*x+bmi*x
H0<-lm(y~1+x+bmi)
H1<-lm(y~1+x+bmi+x*bmi)
anova(H0,H1)
summary(lm(y~1+x+bmi))
But I want to use permutation testing to
