Moving-block bootstrap
[ovb,selb,k,re]=movblockboot(T,l,B)
* T = sample size
* l = block length
* B = number of bootstrap replications
* ovb = (l x T/l) matrix that decomposes the initial sample into l overlapping blocks
* selb = (T/l x B) matrix that randomly selects the overlapping blocks
* k = number of blocks
* re = size of the last block if T/l not an integer
