(v) Test if the contribution of the variable x3 in a model already containing x1, x2, x4
(vi) Test if the contribution of the variables x1, x2 in a model already containing x3, x4
2. Consider the multiple linear regression model
y = β0 + β1x1 + β2x2 + β3x3 + β4x4 + ε
The above model can be represented by y X or It is desired to test
(i) H0: β1 = 2β2, β3 = β4.
(ii) H0: β1 – 2β2 = 4β3, β1 – 3β2 = 0.
(iii) H0: Cβ = 0 where
State the reduced model and d...
