Application of Cox Model to predict the survival of patients with Chronic Heart Failure: A latent class regression approach
A latent class Cox PH model is fitted to CHF survival data with class number selected by BIC, evaluated via AUC on cross-validated and bootstrapped samples, and shown in simulation to outperform the standard single-class Cox model.
