  1. Let X_1, X_2, \ldots, X_n be iid with the following density function

    f(x) = \left\{\begin{array}{cc} (\theta + 1)x^\theta& 0\le x\le 1;\theta>-1 \\ 0 & \mathrm{elsewhere} \end{array} \right.

    Find the MLE for \theta.

  2. Let X_1, X_2, \ldots, X_n be iid with the following density function

    f(x) = \left\{\begin{array}{cc} \frac{1}{\Gamma(\alpha)\theta^\alpha}x^{\alpha-1}e^{-x/\theta} & 0<x;0< \theta \\ 0 & \mathrm{elsewhere} \end{array} \right.

    where \alpha>0 is known. Find the MLE for \theta.

  3. Let X_1, \ldots, X_n\overset{iid}{\sim}Geo(p), what is the MLE of p.
