In this section we compare the results of fitting the logistic growth function and the Gompertz growth function to statistical data series. The first example refers to weight growth of Holstein cows. Data from monthly … WitrynaThe graph of the logistic equation is pictured below. Fig. 1. Graph of a logistic equation. There is a point in the middle of the graph where the graph switches concavity. This is the point that the population growth rate begins to slow down. At first, the growth rate of the logistic growth model is almost identical to the exponential growth model.
