I am new to SEM.
I conducted a survey on students at 3 different types of schools, and there are a few schools of each type, giving me a total of 14 sampling sites (I went to all the schools in my sampling frame). The survey comprised scale-type questions, so my raw data is ordinal, and my SEM assesses the relationships between latent constructs after CFA. I want to account for the nestedness of my data but I'm not sure how to do it. I tried using the lavaan.survey package, but got the following error.
Error in t(x) - xbar : non-numeric argument to binary operator
From reading other discussions, I suppose this is because the package cannot work on ordinal/categorical data yet. In that case, is there any way I can account for clustering? Would appreciate it if anyone could point me to a package or some example syntax.
