It is a sigmoid function … WebThe defining feature of Gompertz growth is that the growth rate decays exponentially as the population approaches it maximum. Gompertz and logistic models generate curves that are very similar. But when Y is low, the Gompertz model grows more quickly than the logistic model. Conversely, when Y is large, the Gompertz model grows more slowly … nust board of directors
