In der vorliegenden Arbeit werden Metamodelle und deren Anwendungen erläutert. Im ersten Teil wird auf die Theorie der Metamodelle eingegangen. Es wird im Speziellen die Herleitung von linearen Regressionsmodellen erläutert. Im Anschluss werden Arten vorgestellt, um Antwortflächen zu beschreiben. Unter den vorgestellten Methoden sind polynomiale Regression, Weighted-Interpolation, Moving-Least-Square-Regression, Radiale-Basis-Funktion-Interpolation, Kriging, Gauß-Prozess-Regression und künstliche neuronale Netzwerke. Im Folgenden wird auf die Validierung von Metamodellen eingegangen. Hierbei werden Fehlermaße, der Determinationskoeffizient, Split-Sampling, Kreuzvalidierung und der Prognosekoeffizient näher behandelt. Als Nächstes werden Met...
