I am currently trying to carry out the Mundlak approach to NELS:88-92 dataset. I was wondering if someone knew how best to use the probability weights the dataset has given in order to make the results less biased and more representative of the total population, as well as deal with the issue of non-response. If I turn the data into 'survey data' I no longer know how to use the Mundlak approach/xthybrid appraoch and so any help with that would also be much appreciated
