Question

Where appropriate, linear regression with one explanatory variable can be performed through the origin', that is, with the intercept α fixed equal to zero. The log-likelihood in this reduced model is So(B) 1(8, o)-constant-n log ơ--2 where 7 (by setting α = 0 in Equations (11.5) and (11.6) in subsection 2.1 of Unit 11). Solve the equation dS。(β)/dd = 0 to provide the candidate value fy for the value of β that minimises So(1) (it can be confirmed that β thus found is the MLE for β but you need not do so.) choose the
