Control variable information

A control variable (or scientific constant) in scientific experimentation is an experimental element which is constant (controlled) and unchanged throughout...

models, controlling for a variable means binning data according to measured values of the variable. This is typically done so that the variable can no...

A variable is considered dependent if it depends on an independent variable. Dependent variables are studied under the supposition or demand that they...

created by a programming error in a condition-controlled loop, wherein the loop condition uses variables that never change within the loop. Sometimes within...

VVC (Variable Valve Control) is an automobile variable valve timing technology developed by Rover and applied to some high performance variants of the...

VTEC (described as Variable Valve Timing & Lift Electronic Control, but stands for Valve Timing Electronically Controlled) is a system developed by Honda...

control is an experiment or observation designed to minimize the effects of variables other than the independent variable (i.e. confounding variables)...

Variable structure control (VSC) is a form of discontinuous nonlinear control. The method alters the dynamics of a nonlinear system by application of...

environment variable is a user-definable value that can affect the way running processes will behave on a computer. Environment variables are part of...

and the final control element (FCE) which controls the process necessary to automatically adjust the value of a measured process variable (PV) to equal...

control a process or operation. The control system compares the value or status of the process variable (PV) being controlled with the desired value or setpoint...

In control theory, a process variable (PV; also process value or process parameter) is the current measured value of a particular part of a process which...

"confounding variables" are minimised to reduce error Control variables, variables which are kept constant during an experiment Biological pest control, a natural...

process variable, called the error signal, or SP-PV error, is applied as feedback to generate a control action to bring the controlled process variable to...

In statistics, bad controls are variables that introduce an unintended discrepancy between regression coefficients and the effects that said coefficients...

settings and variables. Terms are now split into acronyms of CONTROL VARIABLE + BREATH SEQUENCE + TARGETING SCHEME. As in PC-CMV, Pressure Controlled Continuous...

In statistics, a categorical variable (also called qualitative variable) is a variable that can take on one of a limited, and usually fixed, number of...

Pascal, Modula, Oberon, Ada, MATLAB, OCaml, F#, and so on, requires a control variable with start- and end-values, which looks something like this: for i...

The term Variable Control Voice Actuator (VCVA) refers to a digital recording technology developed by Olympus, which is implemented in many of their digital...

A random variable (also called random quantity, aleatory variable, or stochastic variable) is a mathematical formalization of a quantity or object which...

observation of the state variables. Stochastic control aims to design the time path of the controlled variables that performs the desired control task with minimum...

A state variable is one of the set of variables that are used to describe the mathematical "state" of a dynamical system. Intuitively, the state of a...

A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios. This contrasts with...
