Lesson 0: Matrices and Vectors | STAT 505

Definitions of Matrix and Vector. A matrix is two-dimensional array of numbers of formulas. A vector is a matrix with either only one column or only one row. A column vector has only one column. A row vector has only one row. The dimension of a matrix is expressed as number of rows × number of columns.

Scalar Definition: Scalars vs. Vectors (Difference Between

To understand what a vector is we need to define what a scalar is. A scalar is a quantity expressed by a single real number . An example of a scalar is length (which can be measured in inches or feet).

Vector (mathematics and physics) – Wikipedia

Position vector, a vector representing the position of a point in an affine space in relation to a reference point. Poynting vector, in physics, a vector representing the energy flux density of an electromagnetic field. Probability vector, in statistics, a vector with non-negative entries that sum to one.

Probability Vector Definition | Statistics Dictionary

Definition: Probability Vector. The elements of a probability vector give us the outcomes which can occur, of a discrete random variable and the vector as a whole represents the probability mass function of that random variable. Probability vector is a convenient, compact notation for denoting the behaviour of a discrete random variable.

Vector Transformation & Linear Transformation – Statistics

A vector transformation is a specific type of mapping where you associate vectors from one vector space with vectors in another space. The Role of Functions in Vector Transformations Understanding functions is vital to understanding vector transformations.

generalized linear model – Vector calculus in statistics

Vector calculus in statistics. In statistical mechanics and in markov random fields, there is a large prevalence of conservation in the form of currents. The Ising Model, especially at criticality, and its relatives can be studied from the point of view of discrete harmonic and holomorphic functions.

Vector – An R Introduction to Statistics | R Tutorial

Vector. A vector is a sequence of data elements of the same basic type. Members in a vector are officially called components. Nevertheless, we will just call them members in this site. Here is a vector containing three numeric values 2, 3 and 5. And here is a vector of logical values. A vector can contain character strings.

Score (statistics) – Wikipedia

Score (statistics) In statistics, the score, score function, efficient score or informant indicates how sensitive a likelihood function is to its parameter . Explicitly, the score for is the gradient of the log-likelihood with respect to . The score plays an important role in several aspects of inference. For example:
