OLS_c                   Fast least squares
check_model             Checks whether the input 'model' is valid.
example_clustering      An example 'clustering' object. A clustering is
                        a 'List' that splits indexes 1..#num_datapoints
                        to clusters. Each 'List' element corresponds to
                        one cluster. The clustering is not necessarily
                        a partition but it usually is.
example_model           Example regression model and H0.
fastLm                  Fast least squares
get_clustered_eps       Calculate residuals restricted under H0
one_sided_test          One-sided testing
out_pval                Calculates p-value or test decision
r_test_c                Residual randomization test
restricted_OLS_c        Fast least squares with linear constraint
rrinf                   Generic residual randomization confidence
                        intervals
rrinfBase               Generic residual randomization inference This
                        function provides the basis for all other
                        rrinf* functions.
rrinf_clust             Residual randomization inference based on
                        cluster invariances
rrtest                  Generic residual randomization test
rrtest_clust            Residual randomization test under cluster
                        invariances
two_sided_test          Two-sided testing
