Prediction and Inference in Mathematical Modeling

It's fairly intuitive that a model should accurately represent the data. But what exactly does that mean? Fitting the data In order for a model to be useful at all, it should reasonably fit the data. What constitutes 'reasonable' depends on the fitting method as well as the purpose of the model. Prediction If the… Continue reading Prediction and Inference in Mathematical Modeling

What makes a model good?

How can we identify a good mathematical model? Over focusing on one aspect of modeling (fitting, inference) may not be the best approach. Here are 6 qualities that defines a good model: Reflects data accurately Not overly complex Has predictive power Consistent with general knowledge of the system Can be studied mathematically Can be simulated… Continue reading What makes a model good?
