误差变量的英文
error variance
例句与用法
- Skewness and kurtosis statistics for testing normality in ev model
带有误差变量的偏度和峰度正态性检验 - A method of selecting mges that can be deleted is proposed . because too much mges " deletion will result in an ineffective model , mges can not be deleted totally at one time
提出一种线性稳态数据协调中的显著误差变量选择删除算法，以保证在显著误差变量个数过多的情况下原有模型的有效性。 - Application results show the proposed method can deal with mges effectively and provide useful suggestion on instruments checking . thus the number of instruments that must be checked is minimized , the maintenance effort and expense are reduced . 4
叙述了显著误差选择删除算法在炼油工业的实际应用情况，说明了该算法对带有显著误差变量的处理的有效性，并为检修工作提供了合理建议，使得必须检修的传感器数目最少，减小了检修的工作量和检修费用。 - This model is a class of ev model . in this model , regression function that variance yt is about is nonlinear , is not measureable directly and the measurable directly is x , that is errors - in - variance . the method of estimation is more difficult than the usual because x is not measurable directly
本模型属于一类半参数的ev模型，它表明变量y _ i关于( x _ i ， t _ i )的回归函数呈偏线性的形式，且变量x _ i不能直接观测到，所能观测到的是受了误差变量u _ i干扰的变量x _ i ，由于x _ i不能直接观测到，这使得估计的困难加大。
