Journal ArticleDOI

Phase I Statistical Process Control Charts: An Overview and Some Results

TL;DR: An overview of the literature on Phase I parametric control charts for univariate variables data is presented and the joint distribution of the charting statistics is used to control the false alarm probability while designing the charts.
Journal ArticleDOI

Nonparametric (distribution-free) control charts: An updated overview and some results

TL;DR: Both univariate and multivariate nonparametric control charts are reviewed, unlike the past reviews, which did not include the multivariate charts, here they are reviewed.
Journal Article

Distribution-free exponentially weighted moving average control charts for monitoring unknown location

TL;DR: A two-sided nonparametric Phase II exponentially weighted moving average (EWMA) control chart, based on the exceedance statistics, is proposed for detecting a shift in the location parameter of a continuous distribution.
Journal ArticleDOI

Distribution-free exponentially weighted moving average control charts for monitoring unknown location

TL;DR: A two-sided nonparametric Phase II exponentially weighted moving average (EWMA) control chart, based on the exceedance statistics, is proposed in this paper for detecting a shift in the location parameter of a continuous distribution.
Journal ArticleDOI

A nonparametric exponentially weighted moving average signed-rank chart for monitoring location

TL;DR: In this article, a Markov chain approach is used to compute the run-length distribution and the associated performance characteristics of the two-sided NPEWMA-SR chart, and detailed guidelines and recommendations for selecting the chart's design parameters for practical implementation are provided along with illustrative examples.
