public class DRLocalScheme
extends DataPartitionLocalScheme

Data partitioner Disjoint_Random: for each worker, use a permutation multiply P[beg:end,] %*% X, where P is constructed for example with P=table(seq(1,nrow(X)),sample(nrow(X), nrow(X))), i.e., sampling without replacement to ensure disjointness.
