Inadmissibility of invariant estimator of function of scale parameter of several exponential distributions

LK Patra, S Bajpai, N Misra - arXiv preprint arXiv:2302.03420, 2023 - arxiv.org
In various applied areas such as reliability engineering, molecular biology, finance, etc., the
measure of uncertainty of a probability distribution plays an important role. In the present
work, we consider the estimation of a function of the scale parameter, namely entropy of
many exponential distributions having unknown and unequal location parameters with a
common scale parameter. For this estimation problem, we have considered bowl-shaped
location invariant loss functions. The inadmissibility of the minimum risk invariant estimator …
