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
(1) A variable that is given a constant value for a specified application (2) A variable that controls the effect and usage of a command (3) Alterable values that control the effect and usage of a graphics command (4) A constant whose values determine the operation or characteristics of a system In y = ax2 - bx + c; a, b, and c are the parameters of a family of parabolas (5) A variable, t, such that each variable of a related system of variables may be expressed as a function of t
Operations can take parameters Parameters have a type and a direction Parameters with the in direction cannot be changed by the operation's implementation Parameters with the inout and out direction may be changed role A role defines a relationship between entities or between interfaces Each role has a name, and a multiplicity
The equivalent of an argument but associated with the procedure that receives the value of an argument from the calling function The terms parameter and argument, however, are often used interchangeably
A tough word to define In mathematics, it's a variable or an arbitrary constant In MIDI, it's a value assigned at the beginning of an operation Examples: pitch bend, sustain, voice number, volume, reverb
Information used as input to a water quality model or estimated by a water quality model Examples of parameters include: slope from a statistical relationship between two variables, mean annual value or standard deviation of a variable, and number of observations for a particular variable
A constant in a mathematical program, not subject to choice in the decision problem, but one that could vary outside the control of the decisions Examples are supplies, demands, loss factors, exponents and coefficients in polynomial functions (of the decision variables) Not all coefficients are parameters, as many are zero by the logic of the model For example, the only data for a standard transportation problem are the costs, supplies and demands These can depend upon parameters, but the LP matrix does not -- it is the incidence matrix of the network In general, parameters are data-dependent constants, rather than logically fixed for all instances of the model Some parameters are simply units of measurement, such as the amount of energy (Btu) in a ton of coal, whereas some parameters are uncertain, like demand for a product
a constant in the equation of a curve that can be varied to yield a family of similar curves a quantity (such as the mean or variance) that characterizes a statistical population and that can be estimated by calculations from sample data any factor that defines a system and determines (or limits) its performance
Function parameter or template parameter A function parameter is an object that is local to the function and that gets initialized with the value of a function argument in a function call See Chapter 5
A parameter is a value which is usually unknown (therefore it has to be estimated) and it is used to represent a certain population characteristic For example, the population mean is a parameter that is often used to indicate the average value of a quantity A parameter has a fixed value within a population but each sample drawn from the population will have its own value of the statistic that can be used to estimate this parameter For example, the mean of the data in a sample is used to give information about the overall mean in the population from which that sample was drawn
A parameter is a text file, written in code, that contains the formulae of which the fractal is comprised Parameters allow you to save your fractals in code, as opposed to image, format
a variable which can be measured quantitatively; sometimes, an arbitrary constant; associated with populations One of the unknown values that determine a model (See statistic )
A numeric value which characterizes a probability distribution The mean and variance are typical examples Statistics are typically used to estimate parameters
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
A substitution variable consisting of an ampersand followed by a numeral (&1, &2, etc ) You use parameters in a command file and pass values into them through the arguments of the START command
Modifies the action of a UNIX or GCG command Some parameters have values, which modify the parameter (for example -BEGin=100), but not all do (for example -BATch) See also unqualified parameter For more information, see "Using Program Parameters" in Chapter 3, Using Programs
Parameters are factors or limits which affect the way that something can be done or made. That would be enough to make sure we fell within the parameters of our loan agreement. a set of fixed limits that control the way that something should be done (para- ( PARA-) + metron )
One or more objects the client passes to an IDL operation when it invokes the operation Parameters may be declared as "in" (passed from client to server), "out" (passed from server to client), or "inout" (passed from client to server and then back from server to client)
(of a function) A variable that is declared in the parameter list of a function and specifies part of the function's calling protocol Parameters are lexically bound within the function body, and are bound to their initial values when the function is called Dylan supports required parameters, rest parameters, keyword parameters, and next-method parameters
A variable in an SQL statement, marked with a parameter marker or question mark (?) Parameters are bound to application variables and their values retrieved when the statement is executed
A representation that characterizes a part of a model (e g a growth rate), the value of which is determined outside of the model See: exogenous variable
Number or code entered to specify exactly what a given instruction is to do Parameters are an integral part of the datalogger's program instructions Common parameter entries include reps, measurement channels, measurement ranges, input locations, etc Once the instruction number has been entered in a Program Table, the datalogger will prompt for the parameters by displaying the parameter number in the ID Field of the display
