That is, the regression line would tend to overestimate the magnitudes of y . 即回歸線趨于過(guò)高估計(jì)了Y值。
The regression line is derived from a sample and not from the entire population . 樣本回歸線是根據(jù)一個(gè)樣本而不是根據(jù)完全總體推導(dǎo)出來(lái)的。
If the observations used in the analysis extend back in time for several years, the resulting regression line may be too steep . 如果在分析中使用的觀察值擴(kuò)大到幾年以前,那么推導(dǎo)出的回歸直線就會(huì)可能太懸殊。
The standard error of estimate, on the other hand, measures the variability, or scatter, of the observed values around the regression line . 而估計(jì)值的平均誤差,卻是度量觀察值圍繞著回歸直線的變化程度或分散程度。
That is, the regression line would tend to overestimate the magnitudes of y 即回歸線趨于過(guò)高估計(jì)了y值。
Best-fit regression line 最佳擬合回歸線
