Releasing constraints in gamlj

[srk80]

Hi,

I have a 4 item multi group model as described here. Exercise 3A.
https://stats.oarc.ucla.edu/r/seminars/lgm/#s2

Now I would like to release the first item and fix the second item loadings to (1, 1). This is possible in lavaan by setting auto.fix.first = FALSE which is missing in gamlj.

Is there anyway to get 3 decimal points in the usermodel chi-square and Estimate column?

Any help?

Quick followup,

How to release PIF_3 intercept while doing scalar invariance? Seems the group.partial is not effective here.

For the second question, PIF_3 ~ c(a, b)*1 is working.
