Error and runtime of the numerical solution scheme. The accuracy increases with increasing order, but the runtime also increases. Thus, the choice of the order depends on the user’s preferences regarding this balance. a) Error of moment vector from numerical solutions (down-sampled to order 10) when compared to simulations. Mean MSE and absolute error is over all parameter combinations. Max is the maximum among them. b) Runtime of the numerical procedure for different moment orders. Mean is taken over all parameter combinations. Max is the maximum among them.
