1. Correlation (in statistics): A dependence between random variables not necessarily expressed by a rigorous functional relationship. Unlike functional dependence, a correlation is, as a rule, considered when one of the random variables depends not only on the other (given) one, but also on ... (Mathematics) [100%] 2023-10-23
2. Correlation: In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree ... (Statistical concept) [100%] 2023-12-19 [Covariance and correlation] [Dimensionless numbers]...
3. Correlation: Correlation (co-relation) refers to the degree of relationship (or dependency) between two variables. Linear correlation refers to straight-line relationships between two variables. [100%] 2023-12-23 [Linear correlation]
4. Correlation: duality A bijective mapping $ \kappa $ between projective spaces of the same finite dimension such that $ S _ {p} \subset S _ {q} $ implies $ \kappa ( S _ {q} ) \subset \kappa ( S _ {p} ) $. The image of a sum of subspaces under ... (Mathematics) [100%] 2023-12-19
5. Correlation: In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree ...

6. Correlation: Correlation describes the relationship of two factors to one another (see cause and effect). When two factors are found to go together, there are only three explanations. [100%] 2023-03-06 [Statistics]
7. Congelation: Congelation (from Latin: congelātiō, lit. freezing, congealing) was a term used in medieval and early modern alchemy for the process known today as crystallization. (Chemistry) [81%] 2023-08-26 [Alchemical processes]
8. Correction (newspaper): A correction in a newspaper consists of posting a public notice about a typographical error or factual mistake in a previously published article. Newspapers usually have specific policies for readers to report factual errors. (Newspaper) [80%] 2023-12-30 [Error]
9. Correction: CORRECTION ko-rek'-shun (mucar, usually rendered "instruction," is translated "correction" in several passages): The verb from which the noun is derived signifies "to instruct" or "chastise." The idea of chastisement was very closely connected in the Hebrew mind with ... [80%] 1915-01-01
10. Distance correlation: In statistics and in probability theory, distance correlation or distance covariance is a measure of dependence between two paired random vectors of arbitrary, not necessarily equal, dimension. The population distance correlation coefficient is zero if and only if the random ... [70%] 2023-12-21 [Statistical distance] [Theory of probability distributions]...
11. Auto-correlation: of a stochastic process $X_t$ Correlation of the values of $X_t$ and $X_{t+h}$. The term "auto-correlation" , along with the term "correlation function" , is mostly employed in studies of stationary stochastic processes, in which the auto-correlation depends ...

12. Identity correlation: In information systems, identity correlation is a process that reconciles and validates the proper ownership of disparate user account login IDs (user names) that reside on systems and applications throughout an organization and can permanently link ownership of those user ... [70%] 2023-01-01 [Information systems]
13. Correlation coefficient: A correlation coefficient is a numerical measure of some type of correlation, meaning a statistical relationship between two variables. The variables may be two columns of a given data set of observations, often called a sample, or two components of ... (Numerical measure of a statistical relationship between variables) [70%] 2023-02-17 [Mathematical terminology]
14. Gamma-correlation: The two-dimensional distribution of non-negative random dependent variables $ X _ {1} $ and $ X _ {2} $ defined by the density $$ p ( x _ {1} , x _ {2} ) = \ p _ {1} ( x _ {1} ) p _ {2} ( x _ {2 ... (Mathematics) [70%] 2023-10-27
15. Correlation function: A correlation function is a function that gives the statistical correlation between random variables, contingent on the spatial or temporal distance between those variables. If one considers the correlation function between random variables representing the same quantity measured at two ... (Correlation as a function of distance) [70%] 2023-12-20 [Covariance and correlation] [Time series]...
16. Correlation function: of a real stochastic process $ \{ {X ( t) } : {t \in T } \} $ The function in the arguments $ t, s \in T $ defined by $$ B ( t, s) = \ {\mathsf E} [ X ( t) - {\mathsf E} X ( t)] [ X ( s) - {\mathsf E} X ( s)]. $$ For the ... (Mathematics) [70%] 2024-01-04
17. Illusory correlation: In psychology, illusory correlation is the phenomenon of perceiving a relationship between variables (typically people, events, or behaviors) even when no such relationship exists. A false association may be formed because rare or novel occurrences are more salient and therefore ... (Philosophy) [70%] 2023-11-17 [Cognitive biases]
18. Canonical correlation: In statistics, canonical-correlation analysis (CCA), also called canonical variates analysis, is a way of inferring information from cross-covariance matrices. If we have two vectors X = (X1, ..., Xn) and Y = (Y1, ..., Ym) of random variables, and there are correlations ...

19. Canonical correlation: The correlation between linear functions of two sets of random variables determined by the maximization of this correlation subject to certain constraints. In the theory of canonical correlations the random variables $ X _ {1} \dots X _ {s} $ and $ X ... (Mathematics) [70%] 2023-08-20
20. Spatial correlation (wireless): In wireless communication, spatial correlation is the correlation between a signal's spatial direction and the average received signal gain. Theoretically, the performance of wireless communication systems can be improved by having multiple antennas at the transmitter and the receiver. (Wireless) [70%] 2023-12-17 [Telecommunication theory]
