81Mixed model — A mixed model is a statistical model containing both fixed effects and random effects, that is mixed effects. These models are useful in a wide variety of disciplines in the physical, biological and social sciences. They are particularly useful… …
82Document-term matrix — A document term matrix or term document matrix is a mathematical matrix that describes the frequency of terms that occur in a collection of documents. In a document term matrix, rows correspond to documents in the collection and columns… …
83Similarity matrix — A similarity matrix is a matrix of scores which express the similarity between two data points. Similarity matrices are strongly related to their counterparts, distance matrices and substitution matrices.Similarity of Matrix Representations is… …
84Classical XY model — The classical XY model (sometimes also called classical rotor (rotator) model or O(2) model) is a model of statistical mechanics. It is the special case of the n vector model for n = 2. Contents 1 Definition 2 General properties 2.1 One dimension …
85Entity–attribute–value model — (EAV) is a data model to describe entities where the number of attributes (properties, parameters) that can be used to describe them is potentially vast, but the number that will actually apply to a given entity is relatively modest. In… …
86Jaynes-Cummings model — The Jaynes Cummings model (JCM) is a theoretical model in quantum optics. It describes the system of a two level atom interacting with a quantized mode of an optical cavity, with or without the presence of light. The JCM is of great interest in… …
87Rotation matrix — In linear algebra, a rotation matrix is a matrix that is used to perform a rotation in Euclidean space. For example the matrix rotates points in the xy Cartesian plane counterclockwise through an angle θ about the origin of the Cartesian… …
88Markedness Model — The Markedness Model (sociolinguistic theory) proposed by Carol Myers Scotton is one account of the social indexical motivation for code switching. [1] The model holds that speakers use language choices to index Rights and Obligations (RO) Sets,… …
89Bootstrap model — In physics, the term bootstrap model is used for a class of theories that use very general consistency criteria to determine the form of a quantum theory from some assumptions on the spectrum of particles.In the 1960s and 70s, the ever growing… …
