  2. Shewhart individuals control chart - Wikipedia

    The moving ranges involved are serially correlated so runs or cycles can show up on the moving average chart that do not indicate real problems in the underlying process. [ 2 ] : 237 In some cases, it may be advisable to use the median of the moving range rather than its average, as when the calculated range data contains a few large values ...

  3. Row- and column-major order - Wikipedia

    en.wikipedia.org/wiki/Row-_and_column-major_order

    To use column-major order in a row-major environment, or vice versa, for whatever reason, one workaround is to assign non-conventional roles to the indexes (using the first index for the column and the second index for the row), and another is to bypass language syntax by explicitly computing positions in a one-dimensional array.

    Move-to-front (or 'Move to top') - places frequently used, or recently used, information is at the top so it can be found quickly, without having to traverse the whole list. Self-learning Frequency list (or 'Order by access frequency') - re-arranges a list of options in a GUI menu, so that the top ones are the options most commonly selected by ...

  5. Determining the number of clusters in a data set - Wikipedia

    When clustering text databases with the cover coefficient on a document collection defined by a document by term D matrix (of size m×n, where m is the number of documents and n is the number of terms), the number of clusters can roughly be estimated by the formula where t is the number of non-zero entries in D. Note that in D each row and each ...

    At this point, the result of the multiplication is stored in the array and can now be output a row or a column at a time, flowing down or across the array. [4] Systolic arrays are arrays of DPUs which are connected to a small number of nearest neighbour DPUs in a mesh-like topology. DPUs perform a sequence of operations on data that flows ...

    These columns must be separated by spaces or tabs, the latter being recommended for reasons of compatibility between programs. [6] Each row of a file must have the same number of columns. The order of the columns must be respected: if columns of high numbers are used, the columns of intermediate numbers must be filled in.

    New chart types “Pie-of-Pie” and “Bar-of-Pie” break down a slice of a pie as a pie or bar sub-chart respectively (this also enables import of such charts from OOXML files created with Microsoft Office) Text inside chart’s titles, text boxes and shapes (and parts thereof) can now be formatted using the Character dialog; Core / General

    Graphs of probabilities of getting the best candidate (red circles) from n applications, and k/n (blue crosses) where k is the sample size. The secretary problem demonstrates a scenario involving optimal stopping theory [1] [2] that is studied extensively in the fields of applied probability, statistics, and decision theory.
