abstract: Implements the SISAL algorithm by Tikka and Hollmén. It is a sequential
  backward selection algorithm which uses a linear model in a cross-validation setting.
  Starting from the full model, one variable at a time is removed based on the regression
  coefficients. From this set of models, a parsimonious (sparse) model is found by
  choosing the model with the smallest number of variables among those models where
  the validation error is smaller than a threshold. Also implements extensions which
  explore larger parts of the search space and/or use ridge regression instead of
  ordinary least squares.
