  -    this page. Everyone can see the progress which is being made.

  -      Binomial coefficients -- incorporate an "exact" implementation that is
  -      limited to what can be stored in a long.  Also provided double-valued

  -      t-test statistic needs to be added and we should probably add the

  -      The RealMatrixImpl class is missing some key method implementations.

  -      support general linear regression.

  -     <li>
  -      Added double[] |-> double methods in StatUtils to take start indexes and length
