recommendations! Published in 2025 at "Journal of Statistical Computation and Simulation"

DOI: 10.1080/00949655.2025.2492878

Abstract: The maximum likelihood method is often applied by practitioners in a statistical analysis relying on the assumption inferences can be drawn based on asymptotic properties. However, the analysis can be compromised when the sample size… read more here.

DOI: 10.1080/03610926.2022.2050399

Abstract: Exponentiated models have been widely used in modeling various types of data such as survival data and insurance claims data. However, the exponentiated composite distribution models have not been explored yet. In this paper, we… read more here.

DOI: 10.1109/lcomm.2025.3533039

Abstract: Due to its outstanding mathematical tractability, the inverse gamma (InvG) distribution is used as a substitute for the lognormal distribution to characterize the random fluctuations of the wireless signal envelope caused by shadowing. In this… read more here.

DOI: 10.1285/i20705948v11n2p397

Abstract: In this article, acceptance sampling plans are suggested for the life test that is truncated at a preassigned time. The life time of the test units are assumed to follow the inverse-gamma distribution. The minimum… read more here.

DOI: 10.18187/pjsor.v15i1.2238

Abstract: In this article we propose a new weighted version of inverse Gamma distribution known as Weighted Inverse Gamma distribution (WIGD). We examine the Length biased and Area biased versions of Weighted Inverse Gamma distribution. Basic… read more here.
