Dear colleagues,

When I run bootstrapping CB-SEM in smartPLS 4, one indicator will appear "as NaN", seldom in which indicator has constrict value. The notification seems to give information that some bootstrapping failed and suggests checking the execution log. And in the execution log in tells some "...samples failed and will be ignored".

Has anyone had the same trouble? or any have experience with the solution to this problem?

Very much thank you.
