The [tex]X_{i}[/tex] are random sample from the [tex]f\left(x; \theta\right) = \theta x^{\theta - 1}I_{\left(0, 1\right)}\left(x\right)[/tex] where [tex]\theta > 0[/tex].

I need the information in finally solving the Cramer-Rao lower bound for the variance of an unbiased estimator of a function of [tex]\theta[/tex]. And also for checking if I have an unbiased estimator.
