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 |
