Parametrerar

Parametrerar is the Swedish verb meaning to parameterize. It denotes the act of describing a system, model, or function by introducing one or more parameters that control its behavior or shape. The process often involves replacing fixed constants with variables that can be adjusted to fit data, optimize performance, or generalize a solution.

Etymology: The term derives from the English parameterize or the French paramétrer, ultimately from parameter, with the Swedish suffix -era forming the verb.

Användningsområden: In mathematics and geometry, a curve or surface can be described by a parametrization using one or more parameters; for example, a curve may be given by x(t) and y(t). In statistics and econometrics, a model is parametrized by a vector θ, and parameter estimation uses data to infer θ. In software development, parameterization makes components configurable, supports parameterized tests, and enables parameterized queries that separate code from data.

The core idea is to express a concept, equation, or process in terms of adjustable values rather than fixed constants.
