WebOct 23, 2015 · To find the value of the intercept, you don't actually need a regression. 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) WebAn intercept is included in the fixed-effects model by default. If no fixed effects are specified, only this intercept term is fit. The intercept can be removed by using the NOINT option. Table 56.6 summarizes options in the MODEL statement. These are subsequently discussed in detail in alphabetical order.
