Minitab has released version 16.2 of its statistical software package, adding new tools. The update is free for Minitab 16 users.
The Minitab 16.2 update adds four new control charts to those already available in the software: Laney P' and U' charts, and G and T charts. Laney P' and U' control charts are similar to the traditional P and U charts used to monitor processes in many industries. But where traditional control charts can potentially indicate that a stable process is out of control, especially when large amounts of data are collected, Laney charts ensure that only important deviations in the process are detected.
