In particular, [[linear regression]] techniques are much more efficient than most non-linear techniques.<br /> <br /> The model can be [[deterministic]] or [[stochastic]] (i.e. containing random components) depending on its planned use.<br /> <br /> == See also ==<br /> <br /> * [[Computational modelling]]<br /> * [[Computer experiment]]<br /> * [[Computer simulation]]<br /> * [[Design of experiments]]<br /> * [[Grey box testing]]<br /> * [[Linear regression]]<br /> * [[Mathematical model]]<br /> * [[Nonlinear system identification]]<br /> * [[Parameter estimation]]<br /> * [[Research design]]<br /> * [[Scientific modelling]]<br /> * [[Simulation]]<br /> * [[Statistics]]<br /> * [[Statistical model]]<br /> * [[Stochastic process]]<br /> * [[System dynamics]]<br /> * [[System identification]]<br /> * [[System realization]]<br /> * [[Systems theory]]<br /> <br /> == External links ==<br /> <br /> * [https://en.wikipedia.org/wiki/Grey_box_model Grey box model] @ Wikipedia<br /> <br /> <br /> [[Category:Computer science]]<br /> [[Category:Mathematics]]<br /> [[Category:Models]]<br /> [[Category:Statistics]]</div>
