Before revision:  Using systematic simulations , we propose a parsimonious (three-parameter) model of these ratess-R\'enyi } and  show that different wellknown network families map onto distinct regions of the parameter space of this model.
After revision:  Using systematic simulations , we propose a parsimonious (three-parameter) model of these ratess-R\'enyi } and Barab\'asi-Albert networks to build network class-specific priors for these rates. \% show that different wellknown network families map onto distinct regions of the parameter space of this model.
