+        Note that the last iteration may remove fewer than ``step`` features in
+        order to reach ``min_features_to_select``.
+    min_features_to_select : int, (default=1)
+        The minimum number of features to be selected. This number of features
+        will always be scored, even if the difference between the original
+        feature count and ``min_features_to_select`` isn't divisible by
+        ``step``.
+    cv : int, cross-validation generator or an iterable, optional
+        Determines the cross-validation splitting strategy.
+        Possible inputs for cv are:
+        - None, to use the default 3-fold cross-validation,
+        - integer, to specify the number of folds.
+        - :term:`CV splitter`,
+        - An iterable yielding (train, test) splits as arrays of indices.
+        For integer/None inputs, if ``y`` is binary or multiclass,
+        :class:`sklearn.model_selection.StratifiedKFold` is used. If the
+        estimator is a classifier or if ``y`` is neither binary nor multiclass,
+        :class:`sklearn.model_selection.KFold` is used.
+        Refer :ref:`User Guide <cross_validation>` for the various
+        cross-validation strategies that can be used here.
+        .. versionchanged:: 0.20
+            ``cv`` default value of None will change from 3-fold to 5-fold
+            in v0.22.
+    scoring : string, callable or None, optional, (default=None)
+        A string (see model evaluation documentation) or
+        a scorer callable object / function with signature
+        ``scorer(estimator, X, y)``.
+    verbose : int, (default=0)
+        Controls verbosity of output.
+    n_jobs : int or None, optional (default=None)
+        Number of cores to run in parallel while fitting across folds.
+        ``None`` means 1 unless in a :obj:`joblib.parallel_backend` context.
+        ``-1`` means using all processors. See :term:`Glossary <n_jobs>`
