Abstract

Two important statistical parameter estimation pitfalls, examples of which can be found in the literature, are here reviewed and discussed. The first concerns the lack of model qualitative behaviour analysis before proceeding to the actual parameter estimation phase: this may give rise in the worst cases to aberrant model behaviour and to meaningless parameter estimates. The second concerns the use of interpolated noisy observations taken to represent the real input or driving variable into a model: this gives rise to the artifactual reproduction of meaningful features of the output variables, based on data errors and hence inherently non-reproducible. This is particularly dangerous when using noisy observations instead of model predictions in coupled systems. Examples of these pitfalls are drawn from existing glucose-insulin modelling literature and recommendations are made.
