Suppose that we have data y = (y₁,...,yn). Each data-point y; is assumed to be generated by a
distribution with the following probability density function:
8²
p(y; | 0) = = = = exp( - ), y₁ ≥ 0.
The unknown parameter is 0, with 0 > 0.
(a) Write down the likelihood for given y. Find an expression for the maximum likelihood
estimate (MLE) 8.
(b) A Gamma(a,ß) distribution is chosen as the prior distribution for 8. Derive the resulting
posterior distribution for 8 given y.
