Transformation of lagged variable with mother variable excluded (Q867)

The information in this article applies to: 
SIMCA 14.1
SIMCA 14
SIMCA 13
Symptoms: 

Lagged variables are normally scaled and transformed as their original (mother) variable. If the original variable is excluded, the scaling factor of the lagged variable where the mother variable was transformed keeps the transformation but uses an incorrect scaling weight.

Workaround: 

In order to get a usable weight, change the scaling of the lagged variable to UV (instead of Lag).

Status: 

Fixed in SIMCA 15.

More Information: 

Under investigation.
