nounEtymology From super- + statistic.

A mathematical combination of two or more unrelated statistics
- Our superstatistic value is a weighted sum of two components, (i) a powerlaw corrected by the lower incomplete gamma function, which asymptotically tends toward robustness but initially gives an exponential, and (ii) a powerlaw damped by the upper incomplete gamma function, which tends toward the power-law only during short interevent times.2015, Mateusz Denys, Maciej Jagielski, Tomasz Gubiec, Ryszard Kutner, H.
