1. Covariance and correlation: In probability theory and statistics, the mathematical concepts of covariance and correlation are very similar. Both describe the degree to which two random variables or sets of random variables tend to deviate from their expected values in similar ways.

1. Covariance: In probability theory and statistics, covariance is a measure of the joint variability of two random variables. If the greater values of one variable mainly correspond with the greater values of the other variable, and the same holds for the ...

2. Covariance: The covariance — usually denoted as Cov — is a statistical parameter used to compare two real random variables on the same sample space (more precisely, the same probability space). It is defined as the expectation (or mean value) of the product ... [73%] 2023-02-02
3. Covariance: Covariance is a measure of the linear dependence of two variables. If two variables tend to vary in the same direction, then they have a positive covariance. [73%] 2023-02-11 [Probability and Statistics]
4. Covariance: $ \DeclareMathOperator{\cov}{cov} $ $ \DeclareMathOperator{\var}{var} $ $ \DeclareMathOperator{\E}{\mathbf{E}} $ A numerical characteristic of the joint distribution of two random variables, equal to the mathematical expectation of the product of the deviations of these two random variables from their mathematical ...

5. Covariance: Covariance in probability theory and statistics is a measure of the joint variability of two random variables. The sign of the covariance, therefore, shows the tendency in the linear relationship between the variables.

6. 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) [66%] 2023-10-23
7. 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 ...

8. 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. [66%] 2023-12-23 [Linear correlation]
9. 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) [66%] 2023-12-19

11. 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. [66%] 2023-03-06 [Statistics]
12. Covariance and contravariance (computer science): Many programming language type systems support subtyping. For instance, if the type Cat is a subtype of Animal, then an expression of type Cat should be substitutable wherever an expression of type Animal is used.
