@ThingworxExtensionApiClass(since={8,1,1})
public interface IStatistic<V,Q>
extends IMetric

A metric that tracks statistical information for numeric values.

Statistic metrics are tracked via a histogram. Values fed into the histogram are sorted into quantiles and tracked by counts; as a result, the raw values are not stored and cannot be retrieved. Typical statistical information is available, including min/mean/max values, as well as a standard set of percentiles.
