Herbejie Rose,
You could use the boot() function in the R package boot. For example:
# example data matrix
m <- matrix(sample(11*10), ncol=10)
# function to calculate column means for indexed rows of matrix
myfun <- function(data, i) {
apply(data[i, ], 2, mean)
}
# 1000 bootstrap samples

Good evening! This is Herbejie Rose
I need your help for me to compute the following:
I just want to ask on how to bootstrap a 11x10 matrix to obtain 1000
bootstrap samples and compute the 10 dimensional mean per bootstrap sample.
the 11x10 dimension of the matrix has 11 subjects and 10 variable
2 matches
