  5. def apply(x: MatriD, y: VectoD, fname: Strings, hparam: HyperParameter): LassoRegression

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

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

    x

    the data/input m-by-n matrix (augment with a first column of ones to include intercept in model)

    y

    the response/output m-vector

    fname

    the feature/variable names (use null for default)

    hparam

    the hyper-parameters (use null for default)
