I have lots of gaps in my basic knowledge, and this is one. Hope you can help!
In doing EFA (and other analyses) with binary or ordinal items, I want to compare models using ULS and WLS (and their variants) to decide which estimator works best. Present sample size is about 380 with many skewed 0-4 ordinal items, and I may be using between 80 and 100 items.
I'd appreciate any references you can offer that would help fill in this gap about how to choose the best estimator, vis a vis measurement scale, sample size, generalizability, and model complexity!
