回归平方和SSR(SUM OF SQUARES REGRESSION)为: SSR=∑i=1n(y^i−y¯)2 残差平方和SSE(SUM OF SQUARES ERROR)为: SSE=\sum_{i=1}^{n}{\left( y_i-\hat{y}_i \right)^{2}} 其中令 e_i=y_i-\hat{y}_i 正式证明: R^2=r_{xy}^2=r_{y\bar{y}}^2 决定系数,我们也叫解释...
Fifty 21-day-old white wing pigeons were used to measure their body weight,body size and slaughter performance indexes and then study these data with correlation and regression analysis.The correlation coefficients among body weight,body size and slaughter performance indexes were analyzed.The correlatio...
For gamma populations with integer shape parameters m 2, this paper derives, among other things, the regression function and the conditional distribution function of s given XnF(s | ). The latter is particularly important in determining whether the correct gamma distribution (as identified by its...
