Forward trajectories (no. of simulations=100) for a logistic SDE and approximations. See Table 2 for parameter values. (A) The stochastic logistic growth model (SLGM). (B) The Román-Román and Torres-Ruiz (2012) (RRTR) approximation. (C) The linear noise approximation with multiplicative intrinsic noise (LNAM). (D) The linear noise approximation with additive intrinsic noise (LNAA). (E) Standard deviations of simulated trajectories over time for the SLGM (black), RRTR (red), LNAM (green) and LNAA (blue).
