Example code Error

In the Example code:

To generate sample data
X_train, y_train, X_test, y_test = \
    generate_data(n_train=1000,
                  n_test=100,
                  n_features=3,
                  contamination=0.5,
                  random_state=42)

Here, the `generate_data` function was used improperly.
Should be:
X_train, X_test, y_train, y_test = ...
