A pivot table is a table of values which are aggregations of groups of individual values from a more extensive table (such as from a database, spreadsheet, or business intelligence program) within one or more discrete categories. The aggregations or summaries of the groups of the individual terms might include sums, averages, counts, or other ...
The function (,) is the Student's t-statistic for a new value , to be drawn from the same population as the already observed set of values . Using x = μ {\displaystyle x=\mu } the function g ( μ , X ) {\displaystyle g(\mu ,X)} becomes a pivotal quantity, which is also distributed by the Student's t-distribution with ν = n − 1 ...
In descriptive statistics, the range of a set of data is size of the narrowest interval which contains all the data. It is calculated as the difference between the largest and smallest values (also known as the sample maximum and minimum). [1] It is expressed in the same units as the data. The range provides an indication of statistical ...

Pito Salas is a Curaçaoan-American Cambridge, Massachusetts-based software developer.While working with Lotus ' Advanced Technology Group in 1986, Salas invented the pivot table, a "next-generation" spreadsheet concept that was released by Lotus in 1989, as Lotus Improv.
The method of the second set is continued by doubling the range added and subtracted from the pivot point: R 3 = H + 2×(P − L) = R 1 + (H − L) S 3 = L − 2×(H − P) = S 1 − (H − L) This concept is sometimes, albeit rarely, extended to a fourth set in which the tripled value of the trading range is used in the calculation.

The process of converting a narrow table to wide table is generally referred to as "pivoting" in the context of data transformations. The "pandas" python package provides a "pivot" method which provides for a narrow to wide transformation.
