Hi all,
I have 4 matrices, each having 5 columns and 4 rows .....denoted by
B1,B2,B3,B4.
I have generated a vector of 7 indices, say (1,2,4,3,2,3,1} which refers to
the index of the matrices to be chosen and then appended one on the top of
the next: like, in this case, I wish to have the following mega matrix:
B1over B2 over B4 over B3 over B2 over B3 over B1.
1> How can I achieve this?
2> I don't want to manually identify and arrange the matrices for each
vector of index values generated (for which the code I used is :
index=sample( 4,7,replace=T)). How can I automate the process?
Basically, I am doing bootstrapping , but the observations are actually 4X5
matrices.
Appreciate your help.
Thanks,
Preetam
