Let x have the distribution with pdf $\displaystyle f = \frac {1}{2} \exp {-|x-\theta|} $

Let $\displaystyle X_1...X_5 $ be ordered statistic, x between -inf and inf

Find the likelihood ratio for testing the hypothesis $\displaystyle H_0: \theta=\theta_0 $ against$\displaystyle H_a : \theta not = \theta_0 $

likelihood function= $\displaystyle \Pi \frac {1}{2} \exp {-|x-\theta|} $

Not really sure how to continue?

Any help will be appreciated

Thanks in advance
