The model might be highly accurate with that particular sample, but it has lost its value of predicting for similar samples or representing the characteristics of the population. It has been tailored to fit perfectly one particular sample with all of its flaws, outliers, and other unique characteristics. This can be referred to as “overfitting” a model. It is not only a common but also a tempting pitfall in model construction. After all, who would not love to create THE model of crime prediction?
Again, this one subject has a preference for fruitcake, but he remains the only one. In this case, a preference for fruitcake is associated with only 1% of the sample, which is not nearly as exciting. While this is a simple example, similar errors in judgment, analysis, and interpretation of results based on small, nonrandom samples have been made throughout history, sometimes with tragic consequences. All too frequently, public safety programs and policies are based on relatively small samples with unusual characteristics.
