回归分析是处理变量之间相关关系的数学工具。就分析测试而言,它可以帮助人们确定实验结果与实验条件之间是否存在相关关系以及存在怎样的相关关系,而且也可以根据实验条件的变化和要求去预测实验结果,估计预测值的精度。因此,掌握回归分析方法对分析测试人员是颇为重要的。在分析测试中主要遇到 Regression analysis is a mathematical tool that deals with the correlation between variables. As far as analysis and testing is concerned, it can help people to determine whether there is a correlation between experimental results and experimental conditions and what kind of correlation exists, but also to predict the experimental results and estimate the accuracy of the predicted values ​​according to the changes of experimental conditions and requirements. Therefore, to master the regression analysis method is very important for the analysis of testers. Mainly encountered in the analysis and testing
