predictor error的用法和样例：
例句
- You obviously don't think that you are underestimating or overestimating, so the expected forecast error is zero.
很明显你并不认为你会低估或高估，所以期望预测误差为零。 - By optimizing the model parameters, the obtained RVM model had high fitting abilities, less prediction errors and less standard deviation of prediction errors.
通过优化建模参数，所建相关向量机模型具有较高的拟合能力，且预测误差小，稳健性好。
