Dear All,
I've a 10 by 5 data frame like this
set.seed(1001)
a <- rnorm(10)
b <- rnorm(10)
c <- rnorm(10)
d <- rnorm(10)
e <- rnorm(10)
A <- cbind(a,b,c,d,e)
Each row is one datum. I want to resample within A[,5]. Fit the regression
lines lm(A[,5] ~ A[,1] + A[,2]) and lm(A[,5] ~ A[,3] + A[,4]) to each
bootstrap sample. I don't know how to write the statistics part. Can anybody
help me? Thank you very much.
Regards,
Ray
