回归分析是研究随机现象中变量之间关系的一种数理统计方法,它在工农业生产和科学试验中的应用很广泛。目前袖珍式电子计算器应用也已十分普遍,只要计算器中有回归分析功能键,即可进行简单形式的回归分析,可改变用表格计算的繁琐方法,从而加快了数据处理,减轻了计算工作量。本文以日本SHARP EL-5002计算器为例(广州8031、大连DS-5与及EL-5100计算器均可用于回归分析),介绍使用计算器进行一元和二元回归分析的方法。
Regression analysis is a mathematical statistics method to study the relationship between variables in random phenomena. It is widely used in industrial and agricultural production and scientific experiments. At present, the application of pocket-sized electronic calculators is also very common, as long as there are regression analysis function keys in the calculator, a simple form of regression analysis can be performed, and the cumbersome method of calculating with a table can be changed, thereby speeding up the data processing and reducing the calculation work. the amount. This article uses the Japanese SHARP EL-5002 calculator as an example (Guangzhou 8031, Dalian DS-5 and EL-5100 calculators can be used for regression analysis), introduces the use of calculators for one-way and binary regression analysis method.
