+Nested cross-validated supervised learning classifier.
+######################################################
+
+Predicts a categorical sample metadata column using a supervised learning
+classifier. Uses nested stratified k-fold cross validation for automated
+hyperparameter optimization and sample prediction. Outputs predicted values
+for each input sample, and relative importance of each feature for model
+accuracy.
+
+Parameters
+----------
+table : FeatureTable[Frequency]
+    Feature table containing all features that should be used for target
+    prediction.
+metadata : MetadataColumn[Categorical]
+    Categorical metadata column to use as prediction target.
+cv : Int % Range(1, None), optional
+    Number of k-fold cross-validations to perform.
+random_state : Int, optional
+    Seed used by random number generator.
+n_estimators : Int % Range(1, None), optional
+    Number of trees to grow for estimation. More trees will improve
+    predictive accuracy up to a threshold level, but will also increase
+    time and memory requirements. This parameter only affects ensemble
+    estimators, such as Random Forest, AdaBoost, ExtraTrees, and
+    GradientBoosting.
+estimator : Str % Choices('RandomForestClassifier', 'ExtraTreesClassifier', 'GradientBoostingClassifier', 'AdaBoostClassifier', 'KNeighborsClassifier', 'LinearSVC', 'SVC'), optional
+    Estimator method to use for sample prediction.
+parameter_tuning : Bool, optional
+    Automatically tune hyperparameters using random grid search.
+missing_samples : Str % Choices('error', 'ignore'), optional
+    How to handle missing samples in metadata. "error" will fail if missing
+    samples are detected. "ignore" will cause the feature table and
+    metadata to be filtered, so that only samples found in both files are
+    retained.
+
+Returns
+-------
+predictions : SampleData[ClassifierPredictions]
+    Predicted target values for each input sample.
+feature_importance : FeatureData[Importance]
+    Importance of each input feature to model accuracy.
