SEM condition specific constraints
I try to estimate difference between conditions: do conditions differ in the effort participants put into the task (effort as mediating factor). But it seems that my constraint formula does not work:
For instance, to free the unity of regression constraint I formulated (three conditions):
constraints b11==(b111,112,113)
This does not work. Any hel is welcome

What's your model? What's your lavaan syntax? Your question would benefit from a lot more detail... Personally I'm not sure what you're trying to achieve
