Given that Ps = saturation population, P0 = population at the starting point, P = population at any time t from the starting point, K = constant, t = time in years after the starting point, the population at any time t from the starting point is computed according to the logistic curve model as
1
loge\(\left( {\frac{{{P_s} - P}}{P}} \right) \) – loge \(\left( {\frac{{{P_s} - {P_0}}}{{{P_0}}}} \right) \) = – KPs·t
2
loge\(\left( {\frac{{{P_s} - P}}{P}} \right) \) + loge \(\left( {\frac{{{P_s} - {P_0}}}{{{P_0}}}} \right) \) = KPs·t
3
loge \(\left( {\frac{{{P_s} - P}}{P}} \right)\) – loge \( \left( {\frac{{{P_s} - {P_0}}}{{{P_0}}}} \right) = {(KP_s)}^t\)
4
None of the above
