Dear all,

In the paper: Lanjouw & Schankerman (2004) "Patent quality and research productivity: measuring innovation with multiple indicators" Economic Journal, 114, the authors create a "patent quality index" by estimating a factor model with multiple indicator with one latent common factor. In other words, they use 4 patent related indicators to derive the "patent quality index".

My question is the following:
is it possible to do such a thing with gllamm? and if yes, are there any "tutorials" or references explaining the methodology?

Thanks in advance,
