The research examines the zero-state and the steady-state behavior of the Shiryaev-Roberts (SR) procedure for Markov-dependent count time series, using the Poisson INARCH(1) model as the representative data-generating count process. For the purpose of easier evaluation, the performance is compared to existing CUSUM results from the literature. The comparison shows that SR performs at least as...
Non-parametric control charts based on data depth and resampling techniques are designed to monitor multivariate independent and dependent data.
Phase I
Dependent and independent case
- The depths $ D_F (X_i) $ ordered in ascending order are obtained.
- The lower control limit $ (LCI) $ is calculated as the quantile at the $ \alpha $ level of the observations under null...
Recent improvements in data acquisition technologies have produced data-rich environments in every field. Particularly relevant is the case where data are apt to be modelled as functions defined on multidimensional domain, which are referred to as functional data. A typical problem in industrial applications deals with evaluating the stability over time of some functional quality...
Issue Resolution is a critical process in the manufacturing sector to sustain productivity and quality, especially in the Food and Beverage Industry, where aseptic performance is critical. As a leader in this industry, Tetra Pak has built a database regarding quality events reported by Tetra Pak technicians, each containing domain knowledge from experts. In this paper, we present a model...
