Hi Folks

Does anyone know the above module and what it's inputs mean? The docco is rather terse ...

  use Statistics::Regression;

  # Create regression object
  my $reg = Statistics::Regression->new( "sample regression", [ "const
+", "someX", "someY" ] );

  # Add data points
  $reg->include( 2.0, [ 1.0, 3.0, -1.0 ] );
  $reg->include( 1.0, [ 1.0, 5.0, 2.0 ] );
  $reg->include( 20.0, [ 1.0, 31.0, 0.0 ] );
  $reg->include( 15.0, [ 1.0, 11.0, 2.0 ] );

I was expecting to give a more simple two dimensional input of X and Y values, then get back a vector of Theta values such that...

 $predictedY = $Theta[0] + $X * $Theta[1] + $X**2*Theta[2] ... $X**3*T
+heta[n];

How can I reconcile my expectations with the multidimensional data points in the example?

Thanks in Advance,
R.
