WebThe logistic model can be presented mathematically as: d N d t = r N ( 1 − N) where N is population size, t is time, and r is the intrinsic rate of population growth rate on a per capita basis. In this formulation, without loss of generality the carrying capacity of the population is implicitly defined as equal to 1.
