大家好,請問這個專家的審稿意見該怎么答復(fù)啊,幫幫忙,線性回歸相關(guān)問題

The authors reported the equations of calibration curves and the corresponding correlation coefficients. However, the coefficient of correlation was neither a proof of linearity and proportionality, nor a useful measure of the calibration variability. I think that, at least, the proportionality should be evaluated by calculating the confidence interval of the y-intercepts to check that zero is included. Moreover to evaluate the calibration variability the relative residual standard deviations could be calculated. 大家好,大致情況是這樣的,我的實驗的一部分是線性實驗的,方法學(xué)中的線性驗證; 六個點,濃度對應(yīng)峰面積作的線性回歸;用EXCLE作的,得到了一個R2, correlation coefficient(變異系數(shù)),她說這個變異系數(shù)無法反應(yīng)這個線性,非得要個什么可信區(qū)間,這個(X,Y)六個點怎么得這個可信區(qū)間呢? 大家?guī)兔卮鹨幌,感激不盡 |

非常感謝,這個 1) the proportionality should be evaluated by calculating the confidence interval of the y-intercepts to check that zero is included. 我加上置信區(qū)間:95% confidence interval for intercept ,這樣行么? 2) Moreover to evaluate the calibration variability the relative residual standard deviations could be calculated.z這句話應(yīng)該怎么回答呢? 謝謝您 |
