Then is called a pivotal quantity (or simply a pivot). Pivotal quantities are commonly used for normalization to allow data from different data sets to be compared. It is relatively easy to construct pivots for location and scale parameters: for the former we form differences so that location cancels, for the latter ratios so that scale cancels.
A ancillary statistic is a specific case of a pivotal quantity that is computed only from the data and not from the parameters. They can be used to construct prediction intervals . They are also used in connection with Basu's theorem to prove independence between statistics.
This means that, together with its own spent time, each agent actually loses the total time it took the message to arrive its destination, so the agent is incentivized to help the mechanism achieve the shortest transmission time. The Clarke pivot rule can be used to make the mechanism individually-rational: after paying us the cost, each agent ...

“It’s a pivotal time for the Dallas Wings with a new practice facility and renovated arena on the horizon," Miller said. "No. 1 pick in the 2025 draft. It's truly an exciting time.”
After Charley Hull's sensational win in Saudi Arabia last week, golf fans should maintain their attention on events both off and on the course in the Middle East, writes Iain Carter.
For example, the worst-case occurs when pivoting on the smallest element at each step, such as applying quickselect for the maximum element to already sorted data and taking the first element as pivot each time. If one instead consistently chooses "good" pivots, this is avoided and one always gets linear performance even in the worst case.
Also related is the concept of tent-pole programming, or using popular, well-established television shows scheduled in pivotal time periods to boost the ratings of the shows around them. Used especially for new shows, hammocking is limited to prime time, where "appointment television" is strong.
