How to use the level.predict function in level

md: data['TE.random'],
            left: data['lower.random'],
            right: data['upper.random'],
            experimentalTotal: _.sum(_.map(series, 'experimental.total')),
            controlTotal: _.sum(_.map(series, 'control.total')),

        },
        {
            type: 'Prediction interval',
            md: 0,
            left: data['lower.predict'],
            right: data['upper.predict'],
        },
    ];

    draw(elem, width, series, effects, data['level.predict']);
};
