The target value, T, of the quality characteristic. Upper control limit. Lower control limit. Plotted statistic. In statistical quality control, the CUSUM (or cumulative sum control chart) is a sequential analysis technique developed by E. S. Page of the University of Cambridge. It is typically used for monitoring change detection. [1]
Control charts are classified into Shewhart individuals control chart (ISO 7870-2) [2] and CUSUM(CUsUM)(or cumulative sum control chart)(ISO 7870-4). [ 3 ] Control charts, also known as Shewhart charts (after Walter A. Shewhart ) or process-behavior charts , are a statistical process control tool used to determine if a manufacturing or business ...
Running total. A running total or rolling total is the summation of a sequence of numbers which is updated each time a new number is added to the sequence, by adding the value of the new number to the previous running total. Another term for it is partial sum. The purposes of a running total are twofold. First, it allows the total to be stated ...

A player's Neustadtl Sonneborn–Berger score is calculated by adding the sum of the conventional scores of the players they have defeated to half the sum of the conventional scores of those they have drawn against. The main point is to give more value for a win/draw against a player performing well at the tournament, than for a win/draw ...
Prefix sums are trivial to compute in sequential models of computation, by using the formula y i = y i − 1 + x i to compute each output value in sequence order. However, despite their ease of computation, prefix sums are a useful primitive in certain algorithms such as counting sort, [1] [2] and they form the basis of the scan higher-order function in functional programming languages.
A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. [1][2][3] Spreadsheets were developed as computerized analogs of paper accounting worksheets. [4] The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of ...
