f(x).

**Category:**Matha variable entering into the mathematical form of any statistical distribution such that the possible values of the variable correspond to different distributions.

** ^{*}** Usage: The use of parameter in the newer senses, “limits” or “characteristic” is often strongly criticized. Though the criticized uses are now well established both in educated speech and in edited writing, it is easy to substitute “limits” or “characteristics” if desired.

### Wiktionary

parameter(Noun)

A variable kept constant during an experiment, calculation or similar.

parameter(Noun)

A name in a function or subroutine definition that is replaced by, or bound to, the corresponding actual argument when the function or subroutine is called: a formal parameter.

Roughly, a tuple of arguments could be thought of as a vector, whereas a tuple of parameters could be thought of as a covector (i.e., linear functional). When a function is called, a parameter tuple becomes "bound" to an argument tuple, allowing the function instance itself to be computed to yield a return value. This would be roughly analogous to applying a covector to a vector (by taking their dot product (or, rather, matrix-product of row vector and column vector)) to obtain a scalar.

parameter(Noun)

The value which is passed into the function to instantiate such a name; the argument or actual parameter.

parameter(Noun)

A characteristic or feature that distinguishes something from others

**Origin:** From paramètre, from parametrum, from παρά + μέτρον.

### Webster Dictionary

Parameter(noun)

a term applied to some characteristic magnitude whose value, invariable as long as one and the same function, curve, surface, etc., is considered, serves to distinguish that function, curve, surface, etc., from others of the same kind or family

Parameter(noun)

specifically (Conic Sections), in the ellipse and hyperbola, a third proportional to any diameter and its conjugate, or in the parabola, to any abscissa and the corresponding ordinate

Parameter(noun)

the ratio of the three crystallographic axes which determines the position of any plane; also, the fundamental axial ratio for a given species

### Freebase

Parameter

In its common meaning, the term is used to identify a characteristic, a feature, a measurable factor that can help in defining a particular system. A parameter is an important element to take into consideration for the evaluation or for the comprehension of an event, a project or any situation.
