Regression. SSR = ∑ ( y ^ − y ¯) 2. Total. SST = ∑ ( y ^ − y ¯) 2. Now that we know the sum of squares, we can calculate the coefficient of determination. The r 2 is the ratio of the SSR to the SST. It takes a value between zero and one, with zero indicating the …

In statistics, simple linear regression is a linear regression model with a single explanatory variable. That is, it concerns two-dimensional sample points with one independent variable and one dependent variable (conventionally, the x and y coordinates in a Cartesian coordinate system) and finds a linear function (a non-vertical straight line) that, as accurately as possible, predicts …
