Measure quantifying system's degree of organization.

The parameter space is the space of all possible parameter values that define a particular mathematical model.

Synonym of lattice constant (“a constant which describes the geometry of a unit cell in a crystal lattice”).

(programming) An abstract representation, typically including a name and a type, of a parameter expected to be passed to a method or function.

Distance from center to trajectory.

Characteristic value of entire population.

In probability theory and statistics, a scale parameter is a special kind of numerical parameter of a parametric family of probability distributions.

A free parameter is a variable in a mathematical model which cannot be predicted precisely or constrained by the model and must be estimated experimentally or theoretically.

In statistics, a location parameter of a probability distribution is a scalar- or vector-valued parameter , which determines the "location" or shift of the distribution.
