Mean Absolute Error (MAE) is a statistical metric used to quantify the average magnitude of errors in predictions or forecasts, disregarding their direction. In crypto investing and smart trading, MAE measures the average absolute difference between predicted asset prices or volatility levels and their actual observed values. It provides a direct assessment of forecast accuracy, assigning equal weight to all prediction errors.
Mechanism
The calculation mechanism for MAE involves computing the absolute difference between each predicted value and its corresponding actual value. These absolute differences are then summed, and the total is divided by the number of predictions made. This process ensures that positive and negative errors do not cancel each other, yielding a true measure of average error magnitude, which is particularly useful for evaluating model performance in financial contexts.
Methodology
For systems architects developing quantitative analytics engines, the methodology includes integrating MAE as a primary performance indicator for predictive models. It is applied to assess the accuracy of price prediction algorithms, options pricing models, and various risk assessments. Regular computation of MAE across diverse data sets and model iterations guides model selection, parameter tuning, and the continuous improvement of forecasting capabilities within algorithmic trading systems.
