Let X be a random variable which follows a Poisson distribution with parameter A and the
prior distribution of A follows Ga, B) then the posterior distribution is :

Under absolute error loss function, the Bayes estimator of a parameter is the >
(ಗಿ) Mean of the posterior distribution

(B) Median of the posterior distribution

(0) Mode of the posterior distribution

(D) Mean deviation about mean of फिर posterior distribution

For the linear model ¥ = Xf + ¢, where e is a vector of non-observable random variables with
F(e) =0, then the least square estimate of B is :
