Analysis of the causes of the influence of the industrial economy on the social economy based on multiple linear regression equation

Sources of variation	Sum of squares	Degrees of freedom	The variance
Regression model	$E S S = {\sum ({\hat{Y}}_{i} - \bar{Y})}^{2}$	k	$\sum^{} {({\hat{Y}}_{i} - \bar{Y})}^{2} / k$
Due to the remaining	$R S S = {\sum (Y_{i} - {\hat{Y}}_{i})}^{2}$	n–k–1	${\sum (Y_{i} - {\hat{Y}}_{i})}^{2} / (n - k - 1)$
Total variable	$T S S = \sum^{} {(Y_{i} - \bar{Y})}^{2}$	n–1	$\sum^{} {(Y_{i} - \bar{Y})}^{2} / (n - 1)$
