The regression equations and lookup tables required to implement the Quanjer GLI-2012 predicted values in software can be downloaded from here:
We recommend that you also download the instructions on how to implement the equations into software.

How to implement the equations in software
An updated instruction on how to implement the Quanjer GLI-2012 equations is now available. It contains instructions
- on how to implement the regression equations
- worked examples
- provides links to the lookup tables and software (Windows platform) that allows IT engineers to check whether their implementation leads to the correct output.
