Zero-Inflated Promotion Cure-Rate Models With Frailty and Flexible Activation Schemes.
We propose a zero-adjusted promotion cure-rate regression model that jointly accommodates instantaneous failures (times at or near-zero), a non-susceptible cured fraction, competing risks, and latent heterogeneity modeled with a Gamma frailty. The number of latent causes follows a Poisson distribution and their activat...
