Can you please show how the “hint” matrix is achieved using the two theorems below Hint: Use Theorems 6.9 and 6.3....
theorem 6.3) The system Ax=g is consistent if and only if the rank of [A|g] is equal to the rank of A Theorem 6.9) The linear model y=Xβ + ε, t^Tβ is estimable if and only if there us a solution to the linear system X^TXz=t USE HINT MATRICES given in question below and theorems PLEASE!!!! 3. Consider a linear model with only categorical predictors, written in matrix form as y -X131 +e1 Now suppose we add some continuous predictors,...
