Abstract:
|
It is commonly assumed that all curves are fitted equally well in monitoring functional data. A control chart for monitoring goodness of fit for functional profiles is proposed. The performance of the proposed control chart in Phase I applications is demonstrated using both real-life data and simulated data. It is shown that the parameter estimation of model fitting by the proposed method is likely to be more accuracy. Both linear case and non-linear case are discussed. The use of the proposed chart can be beneficial from a general explanation of its wide applicability to most functional profiles.
