"WebDec 1, 2024 · In this work, we introduce a new cure rate model based on the Flory–Schulz (F-S) distribution. The motivations to introduce this model are: (1) The F-S has a PGF in a simple and closer form, very useful in this cure rate model context; (2) P(M=0)=?[sup.2] also has a simple form. This allows one to, among other things, reparametrize the model ... " - Flory schulz distribution
