In this research we propose a profile monitoring method for sequential monitoring of dose-response curves. Dose-response curve experiments are commonly utilized in agricultural and food production applications. In most of the profile monitoring approaches, it is assumed that the errors are independent and identically distributed random variables. In many practical profile monitoring problems, however, the errors are autocorrelated. In this research we study the effectiveness of mixed-effects models to account for autocorrelation within profiles. We consider a Phase II study and investigate the effectiveness of both parametric and nonparametric regression models in monitoring nonlinear profiles. The application of the method is illustrated on a replicated dose-response experiment.
