Graphical tools and goodness-of-fit tests for right-censored data: 1. Kolmogorov-Smirnov, Crámer-von Mises, and Anderson-Darling tests based on the empirical distribution function for complete data and their extensions for right-censored data. 2. Generalized chi-squared-type tests based on the squared difference between observed and expected counts using random cells with right-censored data. 3. A series of graphical tools such as probability or cumulative hazard plots to guide the decision about the parametric model that best fits the data.
