(1) d P ( t) d t = P ( t) ( a − b ln P ( t)) with initial condition. (2) P ( t 0) = P 0; that is, I will allow the initial time to be any t 0 ∈ R. Clearly, we must look for solutions with P ( t) ≠ 0, lest ln P ( t) be undefined. Bearing this in mind, we may divide (1) through by P ( t) and obtain. shipstation netsuite https://milton-around-the-world.com

WebThe Gompertz curve or Gompertz function is a type of mathematical model for a time series, named after Benjamin Gompertz (1779–1865).
