predictive model error的用法和樣例：
例句
- You obviously don't think that you are underestimating or overestimating, so the expected forecast error is zero.
很明顯你並不認為你會低估或高估，所以期望預測誤差為零。 - By optimizing the model parameters, the obtained RVM model had high fitting abilities, less prediction errors and less standard deviation of prediction errors.
通過優化建模參數，所建相關向量機模型具有較高的擬合能力，且預測誤差小，穩健性好。
