Request for assistance.

[Fatma]

Hello everyone,
I am conducting a multi-group path analysis using PISA data for a study. I am analyzing data from 2015, 2018, and 2025 together, but I have hit a roadblock and cannot proceed. Due to the specific structure of PISA data, I cannot use standard coding methods; I need a code structure that accounts for Plausible Values ​​(PVs) and weighting. Is there anyone who has performed path analysis with PISA data in R and could assist me?

Have a look at the R package brr (and related packages) on the github
site of (my former PhD student) Stijn Debrouwere:
