    A test for the significance of the mean direction and the concentration parameter of a circular distribution. Rao's spacing test - contrasted with Rayleigh test This statistics -related article is a stub .

  3. Circular distribution - Wikipedia

    en.wikipedia.org/wiki/Circular_distribution

    In probability and statistics, a circular distribution or polar distribution is a probability distribution of a random variable whose values are angles, usually taken to be in the range [0, 2π). [1] A circular distribution is often a continuous probability distribution , and hence has a probability density , but such distributions can also be ...

    SageMath is designed partially as a free alternative to the general-purpose mathematics products Maple and MATLAB. It can be downloaded or used through a web site. SageMath comprises a variety of other free packages, with a common interface and language. SageMath is developed in Python.

  5. Circular error probable - Wikipedia

    en.wikipedia.org/wiki/Circular_error_probable

    The original concept of CEP was based on a circular bivariate normal distribution (CBN) with CEP as a parameter of the CBN just as μ and σ are parameters of the normal distribution. Munitions with this distribution behavior tend to cluster around the mean impact point, with most reasonably close, progressively fewer and fewer further away ...

  6. von Mises distribution - Wikipedia

    en.wikipedia.org/wiki/Von_Mises_distribution

    In probability theory and directional statistics, the von Mises distribution (also known as the circular normal distribution or the Tikhonov distribution) is a continuous probability distribution on the circle. It is a close approximation to the wrapped normal distribution, which is the circular analogue of the normal distribution.

  7. Directional statistics - Wikipedia

    en.wikipedia.org/wiki/Directional_statistics

    Directional statistics (also circular statistics or spherical statistics) is the subdiscipline of statistics that deals with directions (unit vectors in Euclidean space, R n), axes (lines through the origin in R n) or rotations in R n. More generally, directional statistics deals with observations on compact Riemannian manifolds including the ...

  8. Circular law - Wikipedia

    en.wikipedia.org/wiki/Circular_law

    This theorem refines the circular law of the Ginibre ensemble. In words, the circular law says that the spectrum of almost surely falls uniformly on the unit disc. and the edge statistics theorem states that the radius of the almost-unit-disk is about , and fluctuates on a scale of , according to the Gumbel law.

  9. Circular uniform distribution - Wikipedia

    en.wikipedia.org/wiki/Circular_uniform_distribution

    A 10,000 point Monte Carlo simulation of the distribution of the sample mean of a circular uniform distribution for N = 3 Probability densities (¯) for small values of . Densities for N > 3 {\displaystyle N>3} are normalised to the maximum density, those for N = 1 {\displaystyle N=1} and 2 {\displaystyle 2} are scaled to aid visibility.
