With this website, we provide some statistical programs for the evaluation of specific test methods / procedures.
These programs are provided freely in the hope that they are useful, but without any warranty.
The programs are made available as Excel-files and can be downloaded from the following table.
Additionally, we will provide online calculators for the programs. Currently, you can use BST, MPN and PODLOD-interlab online, see top menu.
