版主写这么多,却不知道楼主在问什么。人家在问X与Y的回归直线,和Ratio estimate等不是一回事。如果想了解直线回归及其表达方式,可以看看这里:
https://www.vitutor.com/statistics/regression/linear_regressio ...

when the intercept in the regression line between y and x is understood to be zero :y、x回归直线的截距为零。这个和 Y于X的回归直线 是一样的啊。
The regression line of x on y 的意思为 X对Y作图的回归线
这两个的意思还是有点差别的。

对的,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 的用法不合题意,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.
