Description: Implements the SparseStep model for solving regression
problems with a sparsity constraint on the parameters. The SparseStep
regression model was proposed in Van den Burg, Groenen, and Alfons (2017)
<https://arxiv.org/abs/1701.06967>. In the model, a regularization term is
added to the regression problem which approximates the counting norm of
the parameters. By iteratively improving the approximation a sparse
solution to the regression problem can be obtained. In this package both
the standard SparseStep algorithm is implemented as well as a path
algorithm which uses golden section search to determine solutions with
different values for the regularization parameter.
