Information geometry is an interdisciplinary field that applies the techniques of differential geometry to study probability theory and statistics. [ 1 ] It studies statistical manifolds , which are Riemannian manifolds whose points correspond to probability distributions .

The use of descriptive and summary statistics has an extensive history and, indeed, the simple tabulation of populations and of economic data was the first way the topic of statistics appeared. More recently, a collection of summarisation techniques has been formulated under the heading of exploratory data analysis : an example of such a ...
In applications to statistics, the manifold is typically the space of parameters of a parametric family of probability distributions. Condition 3 means that D {\displaystyle D} defines an inner product on the tangent space T p M {\displaystyle T_{p}M} for every p ∈ M {\displaystyle p\in M} .
Algebraic statistics is the use of algebra to advance statistics. Algebra has been useful for experimental design , parameter estimation , and hypothesis testing . Traditionally, algebraic statistics has been associated with the design of experiments and multivariate analysis (especially time series ).
The Consumer Financial Protection Bureau (CFPB) on Wednesday warned that credit card companies devaluing or canceling reward points, cash back or miles rewards programs may be breaking the law.
In statistics, maximum spacing estimation (MSE or MSP), or maximum product of spacing estimation (MPS), is a method for estimating the parameters of a univariate statistical model. [1] The method requires maximization of the geometric mean of spacings in the data, which are the differences between the values of the cumulative distribution ...
