Input data standardisation

Hi,
Before we input the data should we standardise it or mean center it especially when we have some moderating variables to check

Hi,

It is not necessary,
The first step in the algorithm PLS is the standardization, and when you will run the moderation analysis, the SmartPLS has options to mean centered, standardized etc. See release.php

Hi,
You do not need to do this, the algorithm PLS already do it.

Z = (Xi - Xbar)/s.d.

Best regards,
