Characteristics of aggregated waiting time distributions. Symbols: Aggregated distributions with different ranges of . Solid and dashed curves: Theoretical distributions (moved to coincide with the corresponding aggregated distribution) for single sequences with equal to the upper bound of each range. Solid curves: 2 years of observation; dashed curve: 16 years. The distribution for in the range 100–10 000 is shown for both 2 and 16 years of observation.Reuse & Permissions
