How do I add weights in% ~% ? #315
Description
Hellow everyone,
I meet some problems in learning piecewise SEM.
The variables I use have different sample sizes, so I use all 'weights = area' to set the weights when building the model. But some variables are correlated, but it's not clear who affects whom? Or they interact.
So I think I need to use '%~~%' to explian them.
However, I don't know how to do that? or can it do that?
Who can give me some idea? Thank you
