地表移动观测同其它测量一样,不可避免地总有误差。因此,在综合分析之前需对实测资料的可靠性进行评价。为了提高水平移动参数的可靠性,我们采用曲线拟合法求参数的区间估计,其基本思想如下: Q=(?)e_k~2 (1) 在Q为最小条件下,组成并答解法方程,求得参数b_1,进而确定经验公式。并以公式 R=(1-Q/S_(yy))~(-2) (2) 评价经验公式的可靠性。R不仅反映回归效果,同时反映两变量的相关程度。故还需作F检验。经检验回归效果显著,对指定的显著水平α即可给出参数y的区间估计 Surface movement observations, like other measurements, inevitably have errors. Therefore, the reliability of measured data needs to be evaluated before comprehensive analysis. In order to improve the reliability of horizontal movement parameters, we adopt the curve fitting method to get the interval estimation of parameters. The basic idea is as follows: Q = (?) E_k ~ 2 (1) Under the condition of Q is the minimum, Have parameters b_1, and then determine the empirical formula. The reliability of the empirical formula is evaluated by the formula R = (1-Q / S_ (yy)) ~ (-2) (2). R not only reflects the regression effect, but also reflects the correlation between the two variables. It also needs to be F test. The regression test results show significant, for the specified level of significance α can be given a parameter y interval estimates
