In this paper, we deal with the problem of finding a proper relaxation procedure (in the sense that relaxed minimizers can be approximated with ordinary controls) for optimal control problems involving delays in the control variables. For systems involving commensurate delays it is well known that...
Statistical control If you have already collected the data, you can include the possible confounders ascontrol variablesin yourregression models; in this way, you will control for the impact of the confounding variable. Any effect that the potential confounding variable has on the dependent variable...

Adependent variableis one being measured in an experiment, reflecting an outcome. Researchers do not directly control this variable. Instead, they hope to learn something about the relationship between different variables by observing how the dependent variable reacts under different circumstances. ...

The independent variable, controlled by the experimenter, influences the dependent variable, which responds to changes. This dynamic forms the basis of cause-and-effect relationships. Graphing independent and dependent variables follows a standard method in which the independent variable is plotted on the...
