Robust Control Charts for Time Series Data

Croux, C.; Gelper, S.; Mahieu, K. - Tilburg University, Center for Economic Research - 2010

This article presents a control chart for time series data, based on the one-step- ahead forecast errors of the Holt …. Moreover, robustness is important to maintain the reliability of the control chart after the occurrence of alarm observations …. The properties of the new control chart are examined in a simulation study and on a real data example. …

Sequential methodology for signaling business cycle turning points

Golosnoy, Vasyl; Hogrefe, Jens - 2009

The dates of U.S. business cycle are reported by NBER with a considerable delay, so an early notion of turning points is of particular interest. This paper proposes a novel sequential approach designed for timely signaling these turning points. A directional cumulated sum decision rule is...

Univariate and multivariate control charts for monitoring dynamic-behavior processes: A case study

Haridy, Salah; Wu, Zhang - In: Journal of Industrial Engineering and Management (JIEM) 2 (2009) 3, pp. 464-498

The majority of classic SPC methodologies assume a steady-state (i.e., static) process behavior (i.e., the process mean and variance are constant) without the influence of the dynamic behavior (i.e., an intended or unintended shift in the process mean or variance). Traditional SPC has been...
