Shewhart-Type Control Charts for Individual Observations
Journal of Quality Technology, 1993 Several options in designing a Shewhart-type control chart for individual observations are discussed. A number of possible estimators of the standard deviation are considered. A two-stage procedure is suggested for retrospective testing. Finally, it is ..

Quality and Reliability Engineering International, 2003 AbstractSeveral control charts for individual observations are compared. Traditional ones are the well‐known Shewhart individuals control charts based on moving ranges. Alternative ones are non‐parametric control charts based on empirical quantiles, on kernel estimators, and on extreme‐value theory.

Shewhart Control Charts for Individuals with Time-Ordered Data
, 1992 The analysis of time-ordered data is of particular interest to the quality engineer and control statistician to whom the time-series plot is a known as a “run chart”. Deming [1982 pp. 112–114 and 1986 pp. 67, 310–314] has been a strong proponent of the use of run charts for the analysis of process data.
