Let Y₄ be the largest order statistic of a sample of size n = 4 from a distribution with uniform pdf f(x; θ) = 1/θ, 0 < x < θ, zero elsewhere. If the prior pdf of the parameter g(θ) = 2/θ³, 1 < θ < ∞, zero elsewhere, find the Bayesian estimator δ(Y₄) of θ, based upon the sufficient statistic Y₄, using the loss function |δ(y₄) − θ|.
