摘要
给出了一种改进回归分析法,可以同时顾及自变量和因变量的验前精度,从而求得合理的拟合参数。在改进回归分析法的基础上,结合抗差估计原理,给出了抗差回归分析法,这对抵制采样点中粗差的污染具有一定的实际意义。通过对所提方法有效性的验证,说明了这些方法在海道测量的相关应用中是可行的。
An improved regression analysis concerning the prior precision of independent variable as well as dependent variable is proposed in order to acquiring reasonable fitting parameters. Furthermore,the robust regression analysis jointing with the robust method based on the improved regression analysis is introduced,which is significant in rejecting the contamination of the gross in practice. Through the test of these methods,it is shown that they can be used in hydrographic surveying accordingly.
