Web1 Answer Sorted by: 16 This is straightforward from the Ordinary Least Squares definition. If there is no intercept, one is minimizing R ( β) = ∑ i = 1 i = n ( y i − β x i) 2. This is smooth as a function of β, so all minima (or maxima) occur when the derivative is zero. Differentiating with respect to β we get − ∑ i = 1 i = n 2 ( y i − β x i) x i.
