public class XbarR extends ShewhartControlChart
XbarR
is an X-bar chart for monitoring a process using sample ranges.
The control limits are at
where is the grand mean of all of the observations, is the mean of the observed ranges, n is the sample size, and k is the value of the "ControlLimit" attribute for the limit. Additionally, , where R is the range of data from a Gaussian distribution. Therefore is an estimate of the within sample standard deviation. By default, the chart contains an upper control limit with k=3, a lower control limit with k=-3, and a central line equal to . Additional control limits can be added. The methodaddWeco
adds control limits with
k = -2, -1, 1, 2.d2, d3
