ESS：误差平方和
“误差平方和”在统计学和数据分析中是一个核心概念，通常简写为ESS（Error Sum of Squares），以方便快速书写和引用。这一术语广泛用于数学、计量经济学以及各类科学实验领域，用于衡量数据观测值与模型预测值之间的差异程度，是评估模型拟合效果的重要指标之一。
Error Sum of Squares具体释义
Error Sum of Squares的英文发音
例句
- Based on fundamental parameters method, the number of factors in XRF multi-variation calibration system has been estimated through the calculation of PRESS ( predictive residual error sum of squares ) and the analysis of principal component.
- 本方法在基本参数法的基础上，运用交互有效法，通过最小预报残差平方和（PRESS）的计算，对体系进行了主组份分析，确定了该体系中的最佳维数和主要影响因素。
- The calibration models were established by using single wavelength regression, multiple linear regression, principal component regression, partial least square regression and artificial neural network. The accuracy of the calculated results was estimated with predictive residual error sum of squares ( PRESS ).
- 分别用单波长回归、多元线性回归、主成分回归、偏最小二乘回归和人工神经网络等方法建立校正模型，用预测残差平方和评价计算结果的准确性。
- A numerical example of carbonization process in an aluminium-making plant indicates that the PRESS ( Prediction Error Sum of Squares(ESS) ) of the model from our method is lower than that from conventional regressions, and the predictor derived from the present work is more robust.
- 在对某铝厂碳酸化分解数据的处理中得到了比常规方法更低的预报残差和，表明所建模型的预报能力更强。
- To compare the validity of settlement prediction with different principia, superior combination forecasting based on forecasting effective measure is much better than the traditional combination forecasting, which modeled on the minimal value of error sum of squares or the deviation absolute sum.
- 不同机理的沉降预测方法组合时，以误差的平方和或离差绝对值之和最小为准则的组合预测不一定能如实地反映其有效性。
