Factors A must be within 1..JA, and Factors B within 1..JB

DATA, FACTORA and FACTORB must have the same size.

EXAMPLES

  $res=Math::TamuAnova::anova( [88.60,73.20,91.40,68.00,75.20,63.00,53.90,
      69.20,50.10,71.50,44.90,59.50,40.20,56.30,

    [1,1,1,1,1,2,2,2,2,2,3,3,3,3,3,4,4,4,4,4],
    4);
  Math::TamuAnova::printtable( $res );
  $res=Math::TamuAnova::anova_twoway(
    [6,10,11,13,15,14,22,12,15,19,18,31,18,9,12],
    [1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2],
