example_data            Example data with two factors from the
                        replication files of Freyaldenhoven (2025).
find_local_factors      Find the rotation of the loading matrix with
                        the smallest l1-norm, as in 'local_factors()',
                        with additional flexibility.
local_factors           Check whether local factors are present and
                        find the rotation of the loading matrix with
                        the smallest l1-norm.
test_local_factors      Test for the presence of local factors, as in
                        'local_factors()', with additional flexibility.
