Conclusion
Overfitting is a common pitfall in statistical modeling that can lead to misleading interpretations. It often results from creating an overly complex model that fits too closely to the specific data set, at the expense of its ability to generalize to new data. Consequently, it exhibits excellent performance on the training data but poor performance on the test data. Practitioners should strive to balance the complexity of the models with their predictive power, implementing techniques like cross-validation or regularizations in order to prevent overfitting and ensure the model’s validity for new, unseen data.
