Pseudo-BMA Function Definitions

• The key idea with BMA is to combine different models to improve prediction performance.
• BMA works by sampling different weights and then evaluating the performance of the combined model using those weights.
• The key metric for evaluation is RMSE, which is defined as

$$RMSE=\sqrt{\frac{1}{N}\sum_{i=1}^N(y_i-\hat{y}_i)^2}$$

• By repeatedly sampling weights, one can obtain an estimate of the optimal weights according to $RMSE$.
