Estimation App Cost


This application simulates the Xbar control chart, that is one of 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.

The control limits can be placed at 2 or 3 sigma. In addition, it is possible to change the sample size.

In addition, the application simulates the real performance of the Xbar control chart (in-control and out-of-control ARLs) when parameters are estimated in Phase I.

There is a twin application for OSX / MAc available in its store. The application is also available for other operating systems.

At this moment the application languages are Spanish and English.
