Urban Noise Pollution: A Dataset for Spatiotemporal and Environmental Analysis
To establish noise pollution levels in El Mansoura, Egypt during 2023, the current study utilizes all around acoustic data acquired from May to December. Concerning noise control in urban areas, the study focuses on change over time, environmental conditions, as well as legal requirements. The analysis of the 1465 measurements provided the following results: Mean […]
Study on an Extension to Lindley Distribution: Statistical Properties, Estimation and Simulation
Recently, Nedjar and Zeghdoudi [6] proposed a new lifetime model called gamma Lindley distribution. Roozegar and Nadarajah [8] introduced some notes around gamma Lindley distribution including only some statistical properties and estimations depending on the same probability density function which proposed by Nedjar and Zeghdoudi [6]. In fact, the model proposed by Nedjar and Zeghdoudi […]
Bayesian and Non-Bayesian Estimation Methods for Simulating the Parameter of the Akshaya Distribution
The ”Akshaya distribution” is a model one-parameter continuous distribution that has been proposed by [15] for modelling lifetime data from biological research and engineering. This paper presents both the classical and Bayesian estimation methods for the Akshaya’s parameter. The model parameter is determined using the weighted least square estimation (WLSE), least square estimation(LSE), Cramer-von-Mises estimation(CVME), […]
Application of Environmental Data with New Extension of Nadarajah-Haghighi Distribution
The sin extension of the exponential (SExEx) or sin Nadarajah-Haghighi (SNH) distribution, a new extension of the exponential distribution with two parameters, is introduced and studied in this paper. For the SNH distribution, the hazard, survival functions and some sumarized data are explored. Methods for estimating the SNH distribution parameters using maximum likelihood estimation (MLE) […]
Moments of Dual Generalized Order Statistics and Characterization for Transmuted Exponential Model
The relationships for moments of dual generalized order statistics (DGOS) for a transmuted exponential (TEx) model are given in this study. These relations are useful when determining the single and product moments of DGOS for a TEx model recursively. Some expressions for recursive computation of moments for special cases of DGOS from a TEx model […]
Order Statistics of Inverse Pareto Distribution
In this paper we study the distribution of order statistics of the inverse Pareto distribution. We consider the single and product moment of order statistics from inverse Pareto distribution. Also, we establish some recurrence relation for single moments of order statistics. The exact analytical expressions of entropy, residual entropy and past residual entropy for order […]
A New Approach for Model Selection with Two Qualitative Regressors
In social science and statistical literature, ordinal qualitative dependent variable models have received substantial attention in terms of theory and application. However, linear models with ordinal qualitative regressors have been overlooked. In this paper, we propose an approach to regression model selection with two-qualitative regressors, which will be used to build a technique for selecting […]
