Any topological framework requires the development of a theory of errors of characteristic and appropriate mathematical form. The paper develops a form of theory which appears to be appropriate to measurements of position on a sphere. The primary problems of estimation as applied to the true direction, and the precision of observations, are discussed in the subcases which arise. The simultaneous distribution of the amplitude and direction of the vector sum of a number of random unit vectors of…

Suplinzary Expectations dcduced from the probability density functions of Fisher are used to develop furthcr the statistics of points on a sphere. The paper presents unbiased estimators of the
A catastrophe associated with the misuse of Fisher's solution for dispersion on a sphere
Perrin has considered the direction I of a line in a body which is subject to a large number of elementary rotations and obtained an exact expression for the resulting probability distribution of I.
The Power of Parametric Orientation Statistics in the Earth Sciences
The problem of determining reliably the "mean" orientations contained in a series of clusters of axes is discussed. The correct parametric procedure, based on the determination of the eigenvectors of
Distributions for spherical data based on nonnegative trigonometric sums
A family of distributions for a random pair of angles that determine a point on the surface of a three-dimensional unit sphere (three-dimensional directions) is proposed. It is based on the use of
Girdle distributions on a sphere
In palaeo-magnetism, a sample of rock specimens is collected from a site and the direction of remanent magnetism of each specimen is measured. It is found that generally the directions are closely or
Geometrical properties of groups of fault plane solutions
A formal method of analysis is proposed whereby groups of first motion solutions may be examined for evidence of regional patterns of symmetry, abstracting from any particular model of the focus or
Statistical theory of the polarization on the Poincaré sphere.
TLDR
The random nature of light emitters requires that the theory to study polarization must adopt a statistical approach, and here the polarization dynamics on the Poincaré sphere of random light sources is described through the von Mises-Fisher distribution.
Optimal R-estimation of a spherical location
In this paper, we provide R-estimators of the location of a rotationally symmetric distribution on the unit sphere of R k . In order to do so we first prove the local asymptotic normality property of

Investigations involving orientations permeate virtually all branches of the earth sciences. Statistical methodology depends upon the requirements of the subject matter and the availability of
The analysis of three-dimensional orientation data
For many observed orientation patterns of three-dimensional geological data no statistical tests are available that define the probability with which a measured sample represents the parent
