摘要
简单地叙述了误差理论与名词方面的问题。用间接观测平差法分析线性回归方程,用曲线中点比较法选择最优非线性回归方程。尤其是根据散点图曲线的形状分为10大类,并提供了32个回归方程供参考。
Briefly states the issues in error theory and terminology. Linear regression equation is analyzed by using indirect error-smoothing, and nonlinear regression equation is optimally selected by using the method of comparison of midpoint of curve. Ten categories are classified according to the shape of curve of the scattered points, and 32 regression equations are provided as references.
