Distributional data analysis is a branch of nonparametric statistics that is related to functional data analysis.It is concerned with random objects that are probability distributions, i.e., the statistical analysis of samples of random distributions where each atom of a sample is a distribution.
The Analysis of Alternatives (AoA) in the United States is a requirement of military acquisition policy, as controlled by the Office of Management and Budget (OMB) and the United States Department of Defense (DoD). It ensures that at least three feasible alternatives are analyzed prior to making costly investment decisions. [1]
In general, if : () is a linear map that is continuous with respect to the weak topology, then it is not always possible to extend to a map ′: ′ ′ by classic extension theorems of topology or linear functional analysis. [note 7] The “distributional” extension of the above linear continuous operator A is possible if and only if A ...
Distributional semantics [1] is a research area that develops and studies theories and methods for quantifying and categorizing semantic similarities between linguistic items based on their distributional properties in large samples of language data.
Distributionalism can be said to have originated in the work of structuralist linguist Leonard Bloomfield and was more clearly formalised by Zellig S. Harris. [1] [3]This theory emerged in the United States in the 1950s, as a variant of structuralism, which was the mainstream linguistic theory at the time, and dominated American linguistics for some time.

Simple back-of-the-envelope test takes the sample maximum and minimum and computes their z-score, or more properly t-statistic (number of sample standard deviations that a sample is above or below the sample mean), and compares it to the 68–95–99.7 rule: if one has a 3σ event (properly, a 3s event) and substantially fewer than 300 samples, or a 4s event and substantially fewer than 15,000 ...
Distributional cost-effectiveness analysis (DCEA) is an extension of cost-effectiveness analysis (CEA) that incorporates concern for both the average levels of ...
Business analysis is a professional discipline [1] focused on identifying business needs and determining solutions to business problems. [2] Solutions may include a software-systems development component, process improvements, or organizational changes, and may involve extensive analysis, strategic planning and policy development.
