This is similar to Exercise 1 It is simplest to prove it in that framework ...

A data set consists of n = n 1 + n 2 + n 3 observations on

Question:

A data set consists of n = n₁ + n₂ + n₃ observations on y and x. For the first n1 observations, y = 1 and x = 1. For the next n₂ observations, y = 0 and x = 1. For the last n₃ observations, y = 0 and x = 0. Prove that neither (17-18) nor (17-20) has a solution.
