About ARL Xbar and S control charts
This application simulates the Xbar and S control charts, that are someof the tools of statistical quality control, or statistical process control (SPC).
It computes by simulation the ARL for different mean and sigma shifts. Concretely, the shifts are measured by d = (m1 - m0) / sigma0 and by r = sigma1 / sigma0.
In addition, it measures the number of times that each control chart shows an out-of-control alarm. For example, it is possible to see that the Xbar control chart detects sigma shifts too.
On the other hand, there is a tab where it sis possible to simulate the effect of the errors in the estimation of the mean and sigma during Phase I (real in-control and out-of-control ARLs)
There is a twin application for OS X available in its store.
At this moment the application languages are Spanish and English.
