摘要
非参数回归是一种广义的回归方法,它具有直观,对模型要求不严密,计算简单的优点。本文介绍非参数回归的原理及其左GPS水准计算中的应用,通过对两个测区的试算,得出了一些有益的结论。
Nonparametric regression is a generalized regression which has some advantagesof intuition,relaxed restriction on the adopted model and easy computation. The principle ofnonparametric regression and it is application to GPS-leveling prediction are introduced. Fi-nally,the method is demonstrated by test computation of two real GPS-leveling networksand it comes to some valuable conclusions.
