Scaling of lagged variables (Q835)

The information in this article applies to: 
SIMCA 13
SIMCA 14
Symptoms: 

Lagged variables are normally scaled as their original (mother) variable. If the original variable is excluded, the lagged variable is scaled according to the default scaling of the project.

Workaround: 

Use Generated Variables on the Data tab to generate the Lag. The lagged variable can then be scaled independently.

More Information: 

Under investigation.
