Dear Prof. Daniele Porcheddu The exponential, Weibull, Gamma, Log-likelihood, Pareto, Logistic distribution etc. These are the most known probability distribution for modelling survival times. Which of these distribution fits your data best, you can use it. For specific cases (such as censoring, finite ranges (e.g. 0

Wayne Fischer

Daniele, are you saying that the survival rate is constant, or that the hazard rate is constant, or that the hazard ratio is constant?

Daniele Porcheddu

Dear prof. Wayne Fischer , indeed I meant a case in which the survival rate is constant. Thank you for your attention. Daniele

If the survival rate is constant, the survival plot would be a straight line (slope = survival rate = a constant) - right? So, the non-parametric Kaplan-Meier model will work (as in "Keep It Simple").
