In regression analysis, a dummy variable (also known as indicator variable or just dummy) is one that takes a binary value (0 or 1) to indicate the absence...

earliest lists commonly suggested six variables: location size, shape, value, hue, orientation, and grain (pattern spacing). To this list, several additions...

In software design and engineering, the observer pattern is a software design pattern in which an object, named the subject, maintains a list of its dependents...

scheduler pattern delays access to a resource (be it a function, variable, or otherwise) only as long as absolutely needed, the scheduled-task pattern delays...

A visitor pattern is a software design pattern that separates the algorithm from the object structure. Because of this separation, new operations can be...

In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how...

In software engineering, the delegation pattern is an object-oriented design pattern that allows object composition to achieve the same code reuse as inheritance...

A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios. This contrasts with...
