  1. def allForms(x: MatriD): MatriD

    Create all forms/terms for each row/point placing them in a new matrix.

  2. def apply(x: MatriD, y: VectoD, fname: Strings, hparam: HyperParameter, technique: RegTechnique.RegTechnique): QuadRegression

    Create a QuadRegression object from a data matrix and a response vector.

    Create a QuadRegression object from a data matrix and a response vector. This factory function provides data rescaling.

    x

    the initial data/input matrix (before quadratic term expansion)

    y

    the response/output m-vector

    fname

    the feature/variable names (use null for default)

    hparam

    the hyper-parameters (use null for default)

    technique

    the technique used to solve for b in x.t*x*b = x.t*y (use OR for default)
