%description
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.
