For instance, if the variable X has a continuous uniform distribution between 0 and 100 and Y is a dichotomous variable equal to 1 if X ≥ 50 and 0 if X < 50, the Tau-c statistic of X and Y is equal to 1 while Tau-b is equal to 0.707. A Tau-C equal to 1 can be interpreted as the best possible positive correlation conditional to marginal ...
Tau (/ ˈ t aʊ, ˈ t ɔː, ˈ t ɒ /; [1] uppercase Τ, lowercase τ or ; Greek: ταυ) is the nineteenth letter of the Greek alphabet, representing the voiceless dental or alveolar plosive IPA:. In the system of Greek numerals , it has a value of 300.
In physics and engineering, the time constant, usually denoted by the Greek letter τ (tau), is the parameter characterizing the response to a step input of a first-order, linear time-invariant (LTI) system. [1] [note 1] The time constant is the main characteristic unit of a first-order LTI system. It gives speed of the response.
The Kendall tau rank correlation coefficient is a measure of the portion of ranks that match between two data sets. Goodman and Kruskal's gamma is a measure of the strength of association of the cross tabulated data when both variables are measured at the ordinal level.

In statistics, the t distribution was first derived as a posterior distribution in 1876 by Helmert [19] [20] [21] and Lüroth. [22] [23] [24] As such, Student's t-distribution is an example of Stigler's Law of Eponymy. The t distribution also appeared in a more general form as Pearson type IV distribution in Karl Pearson's 1895 paper. [25]
Kendall tau rank correlation coefficient, a measure of rank correlation in statistics; Ramanujan's tau function in number theory; shear stress in continuum mechanics; a type variable in type theories, such as the simply typed lambda calculus; path tortuosity in reservoir engineering; in topology, a given topology
The distribution above is sometimes referred to as the tau distribution; [2] it was first derived by Thompson in 1935. [3] When ν = 3, the internally studentized residuals are uniformly distributed between and +. If there is only one residual degree of freedom, the above formula for the distribution of internally studentized residuals doesn't ...
