Proxy Variable in OECD Database: Application of Parametric Quantile Regression and Median Based Unit Rayleigh Distribution
Iman Mohamed Attia
This paper presents an in-depth exploration of the innovative Median-based unit Rayleigh (MBUR) distribution, previously introduced by the author. This new approach is specifically…
A New One Parameter Unit Distribution: Median Based Unit Rayleigh (MBUR): Parametric Quantile Regression Model
Iman Mohamed Attia
Parametric quantile regression is illustrated for the one parameter new unit Rayleigh distribution called Median Based Unit Rayleigh distribution (MBUR) distribution. The estimatio…
New generalized unit distributions based on order statistics
Iman Mohamed Attia
In the present paper, the author discusses the derivation of unit distributions and the derivation of the generalized form using the order statistics. The author discusses the Kuma…
New Three Different Generators for Constructing New Three Different Bivariate Copulas
Iman Mohamed Attia
In this paper, the author introduces new methods to construct Archimedean copulas. The generator of each copula fulfills the sufficient conditions as regards the boundary and being…
Generalized Method of Moments and Percentile Method: Estimating parameters of the Novel Median Based Unit Weibull Distribution
Iman Mohamed Attia
The Median Based Unit Weibull is a new 2 parameter unit Weibull distribution defined on the unit interval (0,1). Estimation of the parameters using MLE encountered some problems li…
