Coefficient of determination on statcrunch
WebGiven below are the steps to find the regression coefficients for regression analysis. To find the coefficient of X use the formula a = n(∑xy)−(∑x)(∑y) n(∑x2)−(∑x)2 n ( ∑ x y) − ( ∑ x) ( ∑ y) n ( ∑ x 2) − ( ∑ x) 2. To find the constant term the formula is b = (∑y)(∑x2)−(∑x)(∑xy) n(∑x2)−(∑x)2 ( ∑ y) ( ∑ x 2) − ( ∑ x) ( ∑ x y) n ( ∑ x 2) − ( ∑ x) 2. WebThe Coefficient of Determination. The coefficient of determination, R 2, is the percent of the variation in the response variable (y) that can be explained by the least-squares regression line. Looking at the definition, we can see that a higher R 2 is better - the LSR line does a better job of explaining the variation in the response variable.
