Witryna14 wrz 2024 · The logistic model gets its base on the mathematical equation below: \begin{cases} X_{t+1} = X_t + KX_t(1-X_t/C)\\X_0 = 10 \end{cases} Where: K = growth rate. C = Carrying capacity. X_n = The population at a given time. n = Time. The logistic equation is a more realistic model for population growth.
