WebAll the algebra has been taken care of and we are left with some arithmetic to implement to estimate the simple linear regression coefficients. Briefly, we can estimate the coefficients as follows: 1 2 B1 = sum ( (x (i) - mean (x)) * (y (i) - mean (y))) / sum ( (x (i) - mean (x))^2 ) B0 = mean (y) - B1 * mean (x) WebLinearAlgebra.
