Although the use of modelling is not unique in policy terms, the use of such a complicated model to explicitly predict the impact of different policy options is unusual for public health policy.
In our last example we consider a more complicated model of a phenomenon that is called topographic mapping (van Ooyen, 2003).
Explaining the propagator data in the absence of clonal interference is likely to require a complicated model with fine tuning of several parameters, compared to the parsimonious explanation by the minimal clonal interference model.
A more complicated model of the MAPK cascade, involving feedback-induced bistability, has been shown to generate fast-moving signaling waves that might account for long-range propagation [9], [13], [14].
This helps to simplify the model and, as considered in the Discussion, we have no reason to expect that a more complicated model of sensing or use of mental maps would qualitatively change the conclusions drawn from our model.
Some of the missing aspects of the complicated process of nucleosome positioning and the shaping of the underlying sequences may thus be revealed through the assessment of a simple structural property instead of with the use of a complicated model.
The strengths of the FEA software lie in the calculation, solving, and analysis aspects of the modeling, and it is therefore relatively weak in the mesh division aspect of a complicated model.
Because the purpose of this modeling approach is to provide guidance for the design of field studies, it is perhaps not necessary to expend large efforts to develop a complicated model at the front end of the study design.
"Pick the brand that you can afford and like best, but buy the least complicated model of that line," she said.
For the beginning stage when the FEP distribution is usually sufficiently anisotropic (and when the expected gamma ray fluxes are expected much bigger) necessary to use more complicated model of anisotropic diffusion.
