MATRIX MATH

$An undirected graph with adjacency matrix: <math display="block">\begin{bmatrix} 1 & 1 & 0 \\ 1 & 0 & 1 \\ 0 & 1 & 0 \end{bmatrix}.</math>$
$Two different Markov chains. The chart depicts the number of particles (of a total of 1000) in state "2". Both limiting values can be determined from the transition matrices, which are given by <math> \begin{bmatrix} 0.7 & 0\\ 0.3 & 1 \end{bmatrix}</math> (red) and <math> \begin{bmatrix} 0.7 & 0.2\\ 0.3 & 0.8 \end{bmatrix}</math> (black).$

Stochastic matrix

MATRIX USED TO DESCRIBE THE TRANSITIONS OF A MARKOV CHAIN

Transition probability matrix; Markov transition matrix; Markov matrix; Stachastic matrix; Right stochastic matrix; Left stochastic matrix; Markov Matrices; Markov matrices; Probability matrix; Stochastic matrices; Stochastic operator

In mathematics, a stochastic matrix is a square matrix used to describe the transitions of a Markov chain. Each of its entries is a nonnegative real number representing a probability.

Projection matrix

$A matrix, <math>\mathbf{A}</math> has its column space depicted as the green line. The projection of some vector <math>\mathbf{b}</math> onto the column space of <math>\mathbf{A}</math> is the vector <math>\mathbf{x}</math>$

NOTION IN STATISTICS

Hat Matrix; Operator matrix; Yhat; Hat matrix; Annihilator matrix; Residual maker matrix

In statistics, the projection matrix (\mathbf{P}), sometimes also called the influence matrix or hat matrix (\mathbf{H}), maps the vector of response values (dependent variable values) to the vector of fitted values (or predicted values). It describes the influence each response value has on each fitted value.

Zero matrix

MATRIX WHOSE ENTRIES ARE ALL 0

Null matrix; Mortal matrix; Mortal matrix problem; 0 matrix

In mathematics, particularly linear algebra, a zero matrix or null matrix is a matrix all of whose entries are zero. It also serves as the additive identity of the additive group of m \times n matrices, and is denoted by the symbol O or 0 followed by subscripts corresponding to the dimension of the matrix as the context sees fit.

Laplacian matrix

MATRIX REPRESENTATION OF A GRAPH

Laplace matrix; Kirchhoff matrix (of a graph); Kirchhoff matrix; Laplacian matrix of a graph; Graph Laplacian

In the mathematical field of graph theory, the Laplacian matrix, also called the graph Laplacian, admittance matrix, Kirchhoff matrix or discrete Laplacian, is a matrix representation of a graph. Named after Pierre-Simon Laplace, the graph Laplacian matrix can be viewed as a matrix form of the negative discrete Laplace operator on a graph approximating the negative continuous Laplacian obtained by the finite difference method.

Design matrix

MATRIX OF VALUES OF EXPLANATORY VARIABLES OF A SET OF OBJECTS

Data matrix (statistics); Data matrix (multivariate statistics); Model matrix; Regressor matrix

In statistics and in particular in regression analysis, a design matrix, also known as model matrix or regressor matrix and often denoted by X, is a matrix of values of explanatory variables of a set of objects. Each row represents an individual object, with the successive columns corresponding to the variables and their specific values for that object.

Matrix (geology)

GEOLOGICAL TERM FOR THE MASS OF MATERIAL IN WHICH LARGER GRAINS, CRYSTALS OR CLASTS ARE EMBEDDED

Groundmass; Rock matrix; Cementing material

The matrix or groundmass of a rock is the finer-grained mass of material in which larger grains, crystals, or clasts are embedded.
