What are some good references for LCA?
Lazarsfeld PF, Henry NW. Latent structure analysis. Boston: Houghton Mifflin, 1968. Still the standard reference, but it should be supplemented with: Goodman, L. A. Exploratory latent structure analysis using both identifiable and unidentifiable models. Biometrika, 1974, 61, 215-231. A shorter but excellent introduction is: McCutcheon AC. Latent class analysis. Beverly Hills: Sage Publications, 1987. Two good, chapter-length introductions to LCA are: Clogg, C. C. (1995). Latent class models. In G. Arminger, C. C. Clogg, & M. E. Sobel (Eds.), Handbook of statistical modeling for the social and behavioral sciences (Ch. 6; pp. 311-359). New York: Plenum. Rost J, Langeheine R. A guide through latent structure models for categorical data. In J. Rost & R. Langeheine (Eds.), Applications of latent trait and latent class models in the social sciences. New York: Waxmann, 1997. In fact, this entire book is a good introductory resource.
