Methods

Non-parametric (or distribution-free) inferential statistical methods are mathematical procedures for statistical hypothesis testing which, unlike parametric statistics, make no assumptions about the probability distributions of the variables being assessed. The most frequently used tests include

  • Anderson–Darling test
  • Statistical Bootstrap Methods
  • Cochran's Q
  • Cohen's kappa
  • Friedman two-way analysis of variance by ranks
  • Kaplan–Meier
  • Kendall's tau
  • Kendall's W
  • Kolmogorov–Smirnov test
  • Kruskal-Wallis one-way analysis of variance by ranks
  • Kuiper's test
  • Logrank Test
  • Mann–Whitney U or Wilcoxon rank sum test
  • McNemar's test
  • median test
  • Pitman's permutation test
  • Rank products
  • Siegel–Tukey test
  • Spearman's rank correlation coefficient
  • Wald–Wolfowitz runs test
  • Wilcoxon signed-rank test.

Famous quotes containing the word methods:

    The greatest part of our faults are more excusable than the methods that are commonly taken to conceal them.
    François, Duc De La Rochefoucauld (1613–1680)

    I think it is a wise course for laborers to unite to defend their interests.... I think the employer who declines to deal with organized labor and to recognize it as a proper element in the settlement of wage controversies is behind the times.... Of course, when organized labor permits itself to sympathize with violent methods or undue duress, it is not entitled to our sympathy.
    William Howard Taft (1857–1930)

    The ancient bitter opposition to improved methods [of production] on the ancient theory that it more than temporarily deprives men of employment ... has no place in the gospel of American progress.
    Herbert Hoover (1874–1964)
