Problem 85E

Let Y1, Y2, . . . , Yn denote a random sample from the density function given by

where α > 0 is known.

a Find the MLE  of θ.

b Find the expected value and variance of  .

c Show that  is consistent for θ.

d What is the best (minimal) sufficient statistic for θ in this problem?

e Suppose that n = 5 and α = 2. Use the minimal sufficient statistic to construct a 90% confidence interval for θ. [Hint: Transform to a χ 2 distribution.]
