1. case class CubicPolynomial(intercept: Double = .0, a: Double = .0, b: Double = .0, c: Double = .0, aa: Double = .0, ab: Double = .0, ac: Double = .0, bb: Double = .0, bc: Double = .0, cc: Double = .0, aaa: Double = .0, abc: Double = .0, bbb: Double = .0, ccc: Double = .0, regressionResult: Option[Result] = None) extends Product with Serializable

   

   Cubic polynomial function of 3 variables, with some 3-order cross-terms dropped (aab, aac, abb, acc, bbc, bcc) to reduce requirements on size of data needed to fit the polynomial.
