Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name.

The Keys to the White House. The Keys to the White House is a prediction system for determining the outcome of presidential elections in the United States. It was developed by American historian Allan Lichtman and Russian geophysicist Vladimir Keilis-Borok in 1981, adapting prediction methods that Keilis-Borok designed for earthquake prediction.
For the integral of a Gaussian function, see Gaussian integral. [−1, 1] (–1) + (1) = –10 ⁄ composite. () = 73 – 82 – 3 + 3. In numerical analysis, an n -point Gaussian quadrature rule, named after Carl Friedrich Gauss, [1] is a quadrature rule constructed to yield an exact result for polynomials of degree 2n − 1 or less by a ...
t. e. In statistics, linear regression is a statistical model which estimates the linear relationship between a scalar response (dependent variable) and one or more explanatory variables (regressor or independent variable). The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple ...
e. Quantum entanglement is the phenomenon of a group of particles being generated, interacting, or sharing spatial proximity in such a way that the quantum state of each particle of the group cannot be described independently of the state of the others, including when the particles are separated by a large distance.
Sumerian King List at the Electronic Text Corpus of Sumerian Literature. The Sumerian King List (abbreviated SKL) or Chronicle of the One Monarchy is an ancient literary composition written in Sumerian that was likely created and redacted to legitimize the claims to power of various city-states and kingdoms in southern Mesopotamia during the ...
