Web15 dec. 2024 · Since 1 / θ n is decreasing in θ, you must pick the smallest value of θ that is ≥ x ( n), i.e. x ( n). Likewise for U ( − θ, 0), the likelihood is 1 / θ n for θ ≥ − x ( 1) and zero otherwise since the support requires all x i ≥ − θ. So the MLE is − x ( 1). This should make sense since this is just a mirror image of the previous problem.
