  2. Sonneborn–Berger score - Wikipedia

    en.wikipedia.org/wiki/Sonneborn–Berger_score

    The Sonneborn–Berger score is the most popular tiebreaker method used in Round Robin tournaments.However in contrast to Swiss tournaments, where such tiebreaker scores indicate who had the stronger opponents according to final rankings, in Round Robin all players have the same opponents, so the logic is a lot less clear-cut.

    Buchholz Cut 1 (the Buchholz score reduced by the lowest score of the opponents); Buchholz (the sum of the scores of each of the opponents of a player); The greater number of wins; The greater number of wins with Black pieces, not counting forfeits. The U.S. Chess Federation recommends these as the first four tie-breaking methods to be used: [18]

  4. Decision-matrix method - Wikipedia

    en.wikipedia.org/wiki/Decision-matrix_method

    A basic decision matrix consists of establishing a set of criteria and a group of potential candidate designs. One of these is a reference candidate design. The other designs are then compared to this reference design and being ranked as better, worse, or same based on each criterion.

  5. Weighted sum model - Wikipedia

    en.wikipedia.org/wiki/Weighted_Sum_Model

    In decision theory, the weighted sum model (WSM), [1] [2] also called weighted linear combination (WLC) [3] or simple additive weighting (SAW), [4] is the best known and simplest multi-criteria decision analysis (MCDA) / multi-criteria decision making method for evaluating a number of alternatives in terms of a number of decision criteria.

  6. Linear least squares - Wikipedia

    en.wikipedia.org/wiki/Linear_least_squares

    Linear least squares (LLS) is the least squares approximation of linear functions to data. It is a set of formulations for solving statistical problems involved in linear regression, including variants for ordinary (unweighted), weighted, and generalized (correlated) residuals.

  7. Weighted product model - Wikipedia

    en.wikipedia.org/wiki/Weighted_product_model

    The weighted product model (WPM) is a popular multi-criteria decision analysis (MCDA) / multi-criteria decision making (MCDM) method. It is similar to the weighted sum model (WSM) in that it produces a simple score, but has the very important advantage of overcoming the issue of 'adding apples and pears' i.e. adding together quantities measured in different units.

  9. Reduced chi-squared statistic - Wikipedia

    en.wikipedia.org/wiki/Reduced_chi-squared_statistic

    The unbiased weighted estimator of the sample variance can be computed as follows: = = (=) = = (¯). Again, the corresponding standard deviation is the square root of the variance.
