Overfitting

Overfitting

Overfitting a model is when a statistical model begins to describe the random error in the data rather than the relationships between variables. This occurs when the model is too complex. In regression analysis, overfitting can produce misleading R2 values, regression coefficients, and p-values. Frost, J. (n.d.). *Overfitting regression models: Problems, detection, and avoidance*.
