Bayesian Inference of Ammunition Consumption Based on Normal-Inverse Gamma Distribution [PDF]
Discrete Dynamics in Nature and Society, 2022 To address the problems of high cost of new ammunition experiment, few data of field test and low accuracy of consumption prediction, this article proposes a Bayesian estimation method of ammunition consumption based on normal-inverse gamma distribution,

The Inverse Gamma Distribution and Benford's Law [PDF]
The PUMP Journal of Undergraduate Research, 2020 According to Benford's Law, many data sets have a bias towards lower leading digits (about 30% are 1's). The applications of Benford's Law vary: from detecting tax, voter and image fraud to determining the possibility of match-fixing in competitive ...

Approximations for the inverse cumulative distribution function of the gamma distribution used in wireless communication [PDF]
Heliyon, 2020 The use of quantile functions of probability distributions whose cumulative distribution is intractable is often limited in Monte Carlo simulation, modeling, and random number generation.

Pakistan Journal of Statistics and Operation Research, 2019 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 structural properties

Confidence intervals for the coefficient of variation and the difference between coefficients of variation of inverse-gamma distributions [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2022 The aim of this study is to establish new confidence intervals for the single coefficient of variation of an inversegamma distribution using Bayesian methods based on the Jeffreys, reference, and uniform priors and compare them with the Wald method. The

Joint distribution properties of fully conditional specification under the normal linear model with normal inverse-gamma priors [PDF]
Scientific Reports, 2023 Fully conditional specification (FCS) is a convenient and flexible multiple imputation approach. It specifies a sequence of simple regression models instead of a potential complex joint density for missing variables.

The Inverse Gamma Distribution: A New Shadowing Model [PDF]
2019 8th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2019 In this paper, we provide empirical evidence that the inverse gamma distribution is an excellent alternative for the lognormal and gamma distributions which are often used to model shadowing.

Trustworthy Multimodal Regression with Mixture of Normal-inverse Gamma Distributions [PDF]
, 2021 Multimodal regression is a fundamental task, which integrates the information from different sources to improve the performance of follow-up applications. However, existing methods mainly focus on improving the performance and often ignore the confidence of prediction for diverse situations.
