  2. Knot tabulation - Wikipedia

    en.wikipedia.org/wiki/Knot_tabulation

    A small table of all prime knots (excluding mirror images) with 7 crossings or fewer. Ever since Sir William Thomson's vortex theory, mathematicians have tried to classify and tabulate all possible knots. As of May 2008, all prime knots up to 16 crossings have been tabulated. [1]

  3. Contingency table - Wikipedia

    en.wikipedia.org/wiki/Contingency_table

    In statistics, a contingency table (also known as a cross tabulation or crosstab) is a type of table in a matrix format that displays the multivariate frequency distribution of the variables. They are heavily used in survey research, business intelligence, engineering, and scientific research.

  5. Knot theory - Wikipedia

    en.wikipedia.org/wiki/Knot_theory

    In the 1860s, Lord Kelvin's theory that atoms were knots in the aether led to Peter Guthrie Tait's creation of the first knot tables for complete classification. Tait, in 1885, published a table of knots with up to ten crossings, and what came to be known as the Tait conjectures.

    The Interventions class captures investigational treatments, therapeutic treatments, and surgical procedures that are intentionally administered to the subject (with some actual or expected physiological effect) either as specified by the study protocol (e.g., “exposure”), coincident with the study assessment period (e.g., “concomitant ...

  8. Statistical classification - Wikipedia

    en.wikipedia.org/wiki/Statistical_classification

    A common subclass of classification is probabilistic classification. Algorithms of this nature use statistical inference to find the best class for a given instance. Unlike other algorithms, which simply output a "best" class, probabilistic algorithms output a probability of the instance being a member of each of the possible classes. The best ...

  9. Types of periodic tables - Wikipedia

    en.wikipedia.org/wiki/Types_of_periodic_tables

    This table, which is a modernised version of von Bichowsky's table of 1918, [110] has 24 columns and 9 + 1 ⁄ 2 groups. Group 8 forms a connecting link or transitional zone between groups 7 and 1. Unclassified periodic tables defy easy classification: 1891 — Wendt's generation-tree of the elements [111] 1893 — Nechaev's truncated cones [112]
