• Canonical correlation — In statistics, canonical correlation analysis, introduced by Harold Hotelling, is a way of making sense of cross covariance matrices.DefinitionGiven two column vectors X = (x 1, dots, x n) and Y = (y 1, dots, y m) of random variables with finite… …   Wikipedia

• Canonical form (Boolean algebra) — In Boolean algebra, any Boolean function can be expressed in a canonical form using the dual concepts of minterms and maxterms. Minterms are called products because they are the logical AND of a set of variables, and maxterms are called sums… …   Wikipedia

• Canonical transformation — In Hamiltonian mechanics, a canonical transformation is a change of canonical coordinates (mathbf{q}, mathbf{p}, t) ightarrow (mathbf{Q}, mathbf{P}, t) that preserves the form of Hamilton s equations, although it might not preserve the… …   Wikipedia

• Canonical analysis — In statistics, canonical analysis (from Gk. κανων bar, measuring rod, ruler) belongs to the family of regression methods for data analysis. Regression analysis quantifies a relationship between a predictor variable and a criterion variable by the …   Wikipedia

• Canonical quantization — In physics, canonical quantization is one of many procedures for quantizing a classical theory. Historically, this was the earliest method to be used to build quantum mechanics. When applied to a classical field theory it is also called second… …   Wikipedia
