1. Obtain the efficiency of the estimator. Is it a fully efficient estimator? Give reasons to support your conclusions.
Suppose that x1, . . . , xn are a random sample from f(x; θ) = (θ + 1)x^θ , 0 < x < 1
Here the parameter θ must satisfy that θ > −1.
We know I(θ) = n/(1 + θ)^2 and the MOM estimator based on the first moment is ˆθ = (1 − 2¯x)/(¯x − 1)
