正交函数法 meaning in English

method orthogonal function

Aiming at the problem on taking no account of relation of forecast factors and instability of regression results caused by selected factors with no orthonormalization which would bring out error to computational results , monadic linear regression analysis and nature orthonormalization function as well as stepwise regression were integrated to establish forecast models of cold in nanjing and upper respiratory tract infection , cerebral hemorrhage as well as cerebral infarction in jinhua
过去在选择预报因子时没有考虑预报因子间的相关性，挑选的预报因子由于非正交使回归计算的结果不稳定，给计算带来一定的误差。针对这一问题，文章将一元线性回归分析、自然正交函数法( eof )和逐步回归方法结合起来，建立了南京感冒以及金华的上呼吸道感染、脑出血和脑梗塞的发病指数预报模型。并将模型结果与逐步回归法建立的模型进行比较。
