Hi,
In Data Metric, I used "mean 0, Var 1" as the inputs for calculating my model. I think this basically transforms the data into Z-scores as the inputs for PLS calculation.
The report page of SmartPLS shows a section called Manifest Variable Scores (Used), which look like the z-scores.
However, when I use Excel to calculate the z-scores myself, I found that there is a discrepancy. For example, if Excel shows 0.711603, the SmartPLS shows 0.713783. Although not big, but noticeable.
I wonder why there is a discrepancy? Does SmartPLS use Z-score in the calculation? Or it uses a different formula?
Thanks.
