Natural parameter (disambiguation)

In mathematics and related areas, a natural parameter or natural parameterization can refer to:

• The natural parameter of a differentiable curve, its arc length, and the natural parameterization representing points by a function of arc length
• The natural parameter of an exponential family of probability distributions, the function $\eta (\theta )$ over which the distribution is exponential
• The natural parameter in parameterized complexity, describing a computational problem that is parameterized by its output value
