First, all of the prediction errors are within 0.009 of the Threshold Model-based approximation using direct input of data.
Our mixed model was an approximation using health-related indicators with a higher coefficient of determination in a logarithmic and linear approximation for each 5-year age groups.
In Figure 2, we compare the simulation for the full model and for the approximation using the limiting model in the first scaling.
By comparing stochastic simulation of the full model and approximations using the limiting models, we see that the main features of evolution of species numbers are well captured by the limiting models.
However there is a lack of research in the large-scale design optimization area applying MCDM to address further approximation using meta-models.
Solving the model in a mean-field approximation using the value obtained experimentally for r 0 gives a final distribution of disk sizes with one unknown parameter (w / λ ) (Supplemental Information, Supplemental Mathematical Modeling part 1).
The model was validated to a first approximation using data from full-scale sites in Vancouver.
The line current model is a simplified first approximation used in this paper to show that the developed inversion procedure works for real geomagnetic variation data.
The lack of oscillations may be either due to the averaging effect since there is variability in the period in this model, or due to the approximation used to derive the reaction rate equations in the deterministic simulation.
As many of the counts of events were very large, the models rely upon asymptotic normal distribution approximations using a linear regression model.
