Lognormal lifetimes and likelihood-based inference for flexible cure rate models based on COM-Poisson family

Recently, a new cure rate survival model has been proposed by considering the Conway–Maxwell Poisson distribution as the distribution of the competing cause variable. This model includes some of the well-known cure rate models discussed in the literature as special cases. Cancer clinical trials often lead to right censored data and so the EM algorithm can be used as an efficient tool for the estimation of the model parameters based on right …
