3. (a) Suppose that ri,...,In are a random sample having probability density function C: a Here α is restricted to be positive. Determine the MLE of α (b) Suppose that ri, , Vn are a random sample from a geometric distribution ㄨㄧ Here the parameter 0 < θ < I. Determine the MLE of θ and show carefully that it is an MLE: it does not suffice to solve the score equation.

Let Yi = Xiß + d E(eiXi) = 0. You observe (X,, Yi) with XXri where ri is a random error. Derive the probability limit of the OLS estimator in the regression of Yi on X,. For simplicity, assume that EX Er0 Your probability limit should have the form β(1-stuff), where stuff depends only on the population variances of ri and X¡. The correct result will highlight that if stuff < 1 then the probability limit of the OLS estimator...
