  4. (in general use) A limit or boundary that defines the scope of a particular process or activity
    • - they set the parameters of the debate
  1. a constant in the equation of a curve that can be varied to yield a family of similar curves
  2. any factor that defines a system and determines (or limits) its performance
  3. argument: (computer science) a reference or value that is passed to a function, procedure, subroutine, command, or program
  4. a quantity (such as the mean or variance) that characterizes a statistical population and that can be estimated by calculations from sample data
  5. In mathematics, statistics, and the mathematical sciences, a parameter (G: auxiliary measure) is a quantity that serves to relate functions and variables using a common variable (often t) when such a relationship would be difficult to explicate with an equation. ...
  6. In computer programming, a parameter is a special kind of variable, used in a subroutine to refer to one of the pieces of data provided as input to the subroutine. . These pieces of data are called arguments. ...
  7. (Parameters (journal)) Parameters is the quarterly journal of the U.S. Army War College.
  8. A variable kept constant during an experiment, calculation or similar; 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; The value which is passed into the function to instantiate such a ...
  9. (Parameters) Numerical characteristics of populations ie parameters are values, usually unknown (and which therefore have to be estimated), used to represent certain population characteristics. Within a population, a parameter is a fixed value, which does not vary.
  10. (Parameters (in spreadsheets)) Values in spreadsheets that remain constant for any single analysis but that can be varied in subsequent analyses.
  11. (Parameters) A specific measure of the water and its conditions; standard tests for ammonia, nitrite, nitrate, pH, KH, GH, oxygen levels, redox levels, temperature
  12. (Parameters) Colleague variables that are set to one of a number of valid values. Changing parameters will cause a Colleague module to function differently, and allow an institution to set up controls and options to meet their individual needs. Parameters may be referred to as flags or switches. ...
  13. (Parameters) Conditions, guidelines, settings.
  14. (Parameters) HP: 2600, Speed relative to that of a Fingerii (Slow and lumbering).
  15. (Parameters) In OR, the constraint constants (coefficients and right-hand sides), of a mathematical model.MHIOM7e
  16. (Parameters) Located in a URL after a question mark and followed by an equal sign and a return value.
  17. (Parameters) Quantities in a differential equation that are constant. For example, in the differential equation x' = ax, a is a parameter. However, in the system of differential equations x' = ax, a' = 1 a is not a parameter since it is described by a differential equation.
  18. (Parameters) Restrictions affecting the design of a product or system (e.g., size, cost, materials).
  19. (Parameters) The idea that some instructions can be qualified with additional information.
  20. (Parameters) Variables that control the behavior of NCAR Graphics utilities and are typically accessed via parameter-access routines that can retrieve or set the parameter value.
  21. (Parameters) We use this word to refer to the user-specifiable settings for an algorithm. To get a correct and accurate output, it is usually necessary to choose the parameters optimally. ...
  22. (Parameters) are always passed by value. A place for them is allocated on the stack and the argument values are copied into them. Therefore they are for all practical purposes the same as automatic local variables initialized to the argument values, and may be used as variables within the program.
  23. (Parameters) are placeholders that let you pass values to scripts. Parameters only apply to methods and event handlers, and not to properties. They are required by some methods and are optional for others.
  24. (Parameters) are unknown, quantitative measures (e.g., total revenue, mean revenue, total yield or number of unemployed people) for the entire population or for specified domains that are of interest. ...
