Let
x_(1),dots,x_(n)
be a random sample from Bernoulli
(\theta )
, where
0<\theta <1
us unknown. Suppose it is known that
\theta ?
Uniform
(0,1)
. Find the Bayesian estimator for
\theta
. Solution: The prior distribution is We also know that
T=
is sufficient for
\theta
(show by FNFT) and that
T?
(show by mgf technique) Thus, the posterior distribution is
