Since Y = a + b * X + ϵ, then E [Y - b * X] = E [a] + E [ϵ], and by assumption E [a] = a and E [ϵ] = 0, where E [] is the expectation operator. Therefore, a = E [Y - b * X]. Translated into R, this means the intercept a is: b1 <- 1.5 a <- mean (y - b1 * x)

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. fly london maus
