”Y于X的回歸直線“改如何翻譯 “the regression line between Y and X”對嗎?求達人指點 |

對的,用法如下 (ii) Ratio estimate in double sampling Ratio estimate is used mainly when the intercept in the regression line between y and x is understood to be zero. The ratio estimate of the population mean is given by (5.43) where denotes the ratio estimate using double sampling. The variance of the estimate is approximately given by the regression line of Y on X 的用法不合題意,用法如下 In statistical inference based on regression coefficients, yes; in predictive modelling applications, correction is neither necessary nor appropriate. To understand this, consider the measurement error as follows. Let y be the outcome variable, x be the true predictor variable, and w be an approximate observation of x. Frost and Thompson[2] suggest, for example, that x may be the true, long-term blood pressure of a patient, and w may be the blood pressure observed on one particular clinic visit. Regression dilution arises if we are interested in the relationship between y and x, but estimate the relationship between y and w. Because w is measured with variability, the slope of a regression line of y on w is less than the regression line of y on x. |

版主寫這么多,卻不知道樓主在問什么。人家在問X與Y的回歸直線,和Ratio estimate等不是一回事。如果想了解直線回歸及其表達方式,可以看看這里: https://www.vitutor.com/statisti ... ear_regression.html |

The regression line of x on y ,The regression line of y on x 以及The regression line between x and y 的意思的確是不同的。就樓主的問題而言,是The regression line of y on x 即”Y于X的回歸直線“;而The regression line of x on y則為”X于Y的回歸直線“,這在實際當(dāng)中極少這么回歸。The regression line between x and y則不具體指明誰于誰進行回歸,是一種籠統(tǒng)的說法。 |
