/**
  * Loads model x and y sample data, overriding any previous sample. 
  * <b>Cloning is not performed to speed the operation</b>. 
  * Computes and caches QR decomposition of the X matrix.
 * @param y the [n,1] array representing the y sample
 * @param x the [n,k] array representing design matrix
 * @param w the [n,1] array representing the weights
 * @throws IllegalArgumentException if the x and y array data are not
