The function that takes the average of the prediction estimates from different models in the Ensemble tool is the one that computes the mean of the predictions. In ensemble modeling, averaging the predictions is a common technique used to improve the overall accuracy and reduce variance by combining multiple models' outputs. Each model contributes equally to the final prediction, and this approach often leads to better performance compared to individual models.

Using the average helps to stabilize the predictions, as extreme values from any single model can be mitigated by the contributions from others. This method is particularly effective when the models being averaged may have different strengths and weaknesses; the averaging process harnesses the wisdom of the crowd by pooling information from various perspectives.

The other options, such as maximum, median, and quarterly, serve different purposes and do not align with the typical functioning of ensemble methods in predicting by combining outputs from multiple models. For instance, maximum would focus only on the highest prediction, failing to utilize the collective input from all models, while median focuses on the central tendency and may remove valuable information from the extremes. Quarterly, on the other hand, is not applicable in this context as it does not pertain to the statistical averaging of model predictions.
