  2. Effect size - Wikipedia

    en.wikipedia.org/wiki/Effect_size

    In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...

  3. Sunrise equation - Wikipedia

    The above general equation can be also used for any other solar altitude. The NOAA provides additional approximate expressions for refraction corrections at these other altitudes. [1] There are also alternative formulations, such as a non-piecewise expression by G.G. Bennett used in the U.S. Naval Observatory's "Vector Astronomy Software". [2]

  4. Boundary layer thickness - Wikipedia

    en.wikipedia.org/wiki/Boundary_layer_thickness

    The boundary layer thickness, , is the distance normal to the wall to a point where the flow velocity has essentially reached the 'asymptotic' velocity, .Prior to the development of the Moment Method, the lack of an obvious method of defining the boundary layer thickness led much of the flow community in the later half of the 1900s to adopt the location , denoted as and given by

  5. Correlation - Wikipedia

    en.wikipedia.org/wiki/Correlation

    N.B.: the figure in the center has a slope of 0 but in that case, the correlation coefficient is undefined because the variance of Y is zero. In statistics , correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data .

  6. Algorithm - Wikipedia

    en.wikipedia.org/wiki/Algorithm

    Flowchart of using successive subtractions to find the greatest common divisor of number r and s. In mathematics and computer science, an algorithm (/ ˈ æ l ɡ ə r ɪ ð əm / ⓘ) is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation.

  7. Omega - Wikipedia

    en.wikipedia.org/wiki/Omega

    In mathematics and computer science: In complex analysis, the Omega constant, a solution of Lambert's W function [8] In differential geometry, the space of differential forms on a manifold (of a certain degree, usually with a superscript). A variable for a 2-dimensional region in calculus, usually corresponding to the domain of a double integral.
