The general fitting degree only reflects the error of mathematical model.
通常的拟合度仅反映了数学模型误差。
Through testing with related experimental data, the models had high fitting degree and applicability.
通过相关试验数据对模型的检验，结果表明模型的拟合程度高，具有很好的适用性。
The estimation suggests that introducing GARCH, regime-switching and jump effect substantially improves the fitting degree of the spot rate models.
结果表明，引入GARCH、机制转换以及跳跃因子可大大地提高短期利率动态模型的拟合效果。
