...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 variables. Just want to have 11x10 per bootrap sample with replacement and compute the 10 dimensional mean. Hope to have a positive response on this matter.. Thank you so much. Sincerely yours, Herbejie Rose [[alternative HTML version deleted]]
