In the Case of Perfect Multicollinearity, OLS Is Unable to Estimate

question 40

Essay

In the case of perfect multicollinearity, OLS is unable to estimate the slope coefficients of the variables involved. Assume that you have included both X₁ and X₂ as explanatory variables, and that X₂ = X $\begin{array} { l } 2 \\1\end{array}$ , so that there is an exact relationship between two explanatory variables. Does this pose a problem for estimation?
