Evaluation Metrics for Model Assessment
In the realm of stock market prediction, evaluating the model’s accuracy and performance is crucial. Several key metrics are employed to ensure reliability and precision. One such metric is Mean Absolute Error (MAE) which measures the average magnitude of errors between predicted values and actual outcomes without considering direction. By focusing on the magnitude, MAE provides a straightforward evaluation of prediction accuracy.
Another vital metric is Root Mean Square Error (RMSE), which evaluates prediction accuracy by considering the square of the error. RMSE emphasizes larger errors more than smaller ones, making it useful for assessing models where larger discrepancies have a higher impact.
Backtesting strategies play an integral role in this evaluation process. By applying a predictive model to historical data, backtesting evaluates how the model would have performed in real-world scenarios, ensuring predictions hold water against historical trends.
Avoiding overfitting is essential for robust performance. Overfitting occurs when a model learns noise instead of the signal in training data. Techniques such as cross-validation help detect and address overfitting by dividing data into training and validation subsets, confirming that the model’s predictions extend beyond just the training data.
