Parametre vs. Parameter: Decoding the Right Spelling

A limit that affects how something can be done.

A variable, measurable factor that defines a system.

A numerical or other measurable specification.

A distinguishing feature or element.

A set of guidelines or rules.

A constant in an equation that varies in other equations of the same general form, especially such a constant in the equation of a curve or surface that can be varied to represent a family of curves or surfaces.

One of a set of independent variables that express the coordinates of a point.

One of a set of measurable factors, such as temperature and pressure, that define a system and determine its behavior and are varied in an experiment.

Usage Problem A factor that restricts what is possible or what results

A factor that determines a range of variations; a boundary

(Statistics) A quantity, such as a mean, that is calculated from data and describes a population.

Usage Problem A distinguishing characteristic or feature.

A value kept constant during an experiment, equation, calculation, or similar, but varied over other versions of the experiment, equation, calculation, etc.

(sciences) A variable that describes some system (material, object, event, etc.) or some aspect thereof.

(statistics) Any measured quantity of a statistical population that summarises or describes an aspect of the population.

(machine learning) A variable of a model that is trained by a machine learning algorithm.

(programming) An input variable of a function definition, that gets an actual value (argument) at execution time.

An actual value given to such a formal parameter.

A characteristic or feature that distinguishes something from others.

(geometry) 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.

(crystallography) The ratio of the three crystallographic axes which determines the position of any plane.

(crystallography) The fundamental axial ratio for a given species.

A constant number which is part of a theory, function, or calculation, whose value is not determined by the form of the theory or equation itself, and may in some cases be arbitrary assigned.

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.

Any constant number which is required to calculate values of observed phenomena according to a theory, but the value of which must be determined by experiment, and cannot be calculated from the fundamental assumptions of the theory. In general, a theory which has a large number of parameters, though it may accurately predict experimental results, is considered as having less explanatory power and as being less esthetically pleasing than a theory with fewer parameters.

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

The limits, guidelines, or assumptions from within which an activity is carried out; as, new arrivals need to learn the parameters of the research in our department.

A variable used in a calculation within a computer program which must be assigned a value before the calculation can be performed; as, let's plug in the parameters and see what the result is.

A characteristic or element, especially one used as a criterion for evaluation or judgment; as, a useful parameter for determining efficiency.

A constant in the equation of a curve that can be varied to yield a family of similar curves

Any factor that defines a system and determines (or limits) its performance

A quantity (such as the mean or variance) that characterizes a statistical population and that can be estimated by calculations from sample data
