X̄ chart with variable sample size and sampling intervals
(1997-04-01)
Recent theoretical studies have shown that the X̄ chart with variable sampling intervals (VSI) and the X̄ chart with variable sample size (VSS) are quicker than the traditional X̄ chart in detecting shifts in the process. ...
X̄ chart with variable sample size and sampling intervals
(1997-04-01)
Recent theoretical studies have shown that the X̄ chart with variable sampling intervals (VSI) and the X̄ chart with variable sample size (VSS) are quicker than the traditional X̄ chart in detecting shifts in the process. ...
Joint X̄ and R Charts with Variable Sample Sizes and Sampling Intervals
(1999-10-01)
Recent studies have shown that the X̄ chart with variable sampling intervals (VSI) and/or with variable sample sizes (VSS) detects process shifts faster than the traditional X̄ chart. This article extends these studies for ...

Adaptive sample size control charts for attributes
(2001-01-01)
Theoretical results have shown that the X̄ chart with variable sample sizes (VSS) is quicker than the traditional X̄ chart for detecting moderate shifts in the process. The idea is to make the sample size vary depending ...
When is n large enough? Looking for the right sample size to estimate proportions
(Taylor and Francis Ltd., 2019)
The central limit theorem indicates that when the sample size goes to infinite, the sampling distribution of means tends to follow a normal distribution; it is the basis for the most usual confidence interval and sample ...
(X)OVER-BAR CHARTS WITH VARIABLE SAMPLE-SIZE
(Amer Soc Quality Control-asqc, 1994-07-01)
The usual practice in using a control chart to monitor a process is to take samples of size n from the process every h hours This article considers the properties of the XBAR chart when the size of each sample depends on ...
