10.1 绪言本章简要介绍了非线性估计问题。由于最小二乘法的几何方面的知识有助于理解非线性情况下的问题,因而在10.6和10.7节中对这种几何进行了扼要讨论。在本章末尾的文献目录中包括许多论述非线性估计的重要文献,那些建议必读的资料都用星号标明。在以往几章中,通过最小二乘法,我们拟合了对参数是线性的模型,其类型是
10.1 INTRODUCTION This chapter gives a brief introduction to nonlinear estimation problems. Since the geometric knowledge of least squares helps to understand problems in nonlinear situations, this geometry is briefly discussed in Sections 10.6 and 10.7. The bibliographic listing at the end of this chapter includes many important articles that deal with non-linear estimates, and those that are required for compilation are all marked with an asterisk. In the previous chapters, we fit the model that is linear to the parameters by the least-squares method, of the type
