This chapter presents the least squares method in the context of the simplest application, fitting the "best" straight line to given data in order to relate two variables X and Y, and discusses how it can be extended to cases where more variables are involved. A straight line relationship ...
An efficient method is given for computing the best straight line by least squares when there are statistical errors in both coordinates. Exact expressions are obtained for the variances of the slope and intercept. 展开全部 机器翻译 AI理解论文&经典十问 挑战十问 参考文献 被引用 社区问答 参考文...
