We have a new commentary in Molecular Psychiatry entitled “Problems with latent class analysis to detect data-driven subtypes of depression” (PDF; together with the fantastic Hanna van Loo, Rob Wanders & Klaas Wardenaar).
This was a response to numerous papers over the last years that found separate latent classes in depression that may be statistical artifacts and driven by violations of local independence.
