TITLE:	On the Performance of Sequential Procedures for Detecting a Change, and Information Quality (InfoQ)

Abstract

The literature on statistical process control has focused on the Average Run Length ($\text{ARL}$) to an alarm, as a performance criterion of sequential schemes. When the process is in control, $\text{ARL}_0$ denotes the $\text{ARL}$ to false alarm and represents the in-control operating characteristic of the procedure. The average run length from the occurrence of a change to its detection, typically denoted by $\text{ARL}_1$, represents the out-of-control operating characteristic. These indices however do not tell the whole story. The concept of information quality (InfoQ) is defined as the potential of a dataset to achieve a specific (scientific or practical) goal using a given empirical analysis method. InfoQ is derived from the utility ($U$) of applying an analysis ($f$) to a data set ($X$) for a given purpose ($g$). Formally, the concept of Information Quality (InfoQ) is defined as: $\text{InfoQ}(f, X, g) = U(f(X | g))$. In this talk, we suggest the use of probability of false alarm (PFA) and conditional expected delay (CED) as an alternative to $\text{ARL}_0$ and $\text{ARL}_1$ which enhances the information quality (InfoQ) of statistical process control methods. As an extension, we discuss the concept of a system for statistical process control in the context of a life cycle view of statistics (SPCLive).
