Deriving Regression coefficient from Residual Sum of Squares
When Linear Regression equation, y=\hat{\alpha} + \hat{\beta} x, is found from the data, the formula for their coefficients, \hat{\alpha} and \hat{\beta}, are the followings. \hat{\beta} = r_{xy}\frac{s_{y}}{s_{x}} $$ \hat{\alpha} = \bar{y} –...
