Online monitoring of nonlinear profiles using a Gaussian process model with heteroscedasticity

There is extensive research in the monitoring of a process whose characteristics are represented as profiles. However, most current techniques require all observations from each profile to determine the process state. We study the use of a Shewhart chart based on a Gaussian process model with hetero...
