In this paper, we proposed a new cure rate model based on the Nielsen distribution. This model has a simple form for the probability gen-erating function, it includes as a particular case the logarithmic distribution and it is a proposal recently discussed in greater detail in the literature, so its application within the context of cure models is very attractive. The model is parameterized directly in the cure rate, facilitating the comparison among other cure rate models in the literature also parameterized in this term. The estimation is approached based on a Bayesian paradigm. A real data set is considered to illustrate the performance of our proposal. © Brazilian Statistical Association, 2022.
