<p>
Amazon Web Services Cost Explorer always returns the mean forecast as a single point. You can request a
prediction interval around the mean by specifying a confidence level. The higher the confidence level, the more
confident Cost Explorer is about the actual value falling in the prediction interval. Higher confidence levels
result in wider prediction intervals.
