A transmuted version of the generalized half-normal distribution
Proyecciones (Antofagasta), 2019 An extension of the generalized half-normal distribution, given by Cooray and Ananda [5], is proposed and studied. We use the quadratic rank transmutation map to generate a transmuted version of the generalized half-normal distribution. We study some probability properties, discuss maximum likelihood estimation and present real data application ...

Gibrat's law for cities: uniformly most powerful unbiased test of the Pareto against the lognormal
, 2009 We address the general problem of testing a power law distribution versus a log-normal distribution in statistical data. This general problem is illustrated on the distribution of the 2000 US census of city sizes.

Measuring Cost Efficiency Of Ukrainian Banks In 2008 [PDF]
, 2012 The paper presents the results of a stochastic frontier analysis (SFA) of cost-efficiency of Ukrainian banks. As of lack of data on the personnel costs, we had to set limits to the year of 2008 only.

Linear Mixed Models with Marginally Symmetric Nonparametric Random Effects
, 2016 Linear mixed models (LMMs) are used as an important tool in the data analysis of repeated measures and longitudinal studies. The most common form of LMMs utilize a normal distribution to model the random effects.

Distribution of equilibrium edge currents
, 2003 We have studied the distribution of equilibrium edge current density in 2D system in a strong (quantizing) magnetic field. The case of half plane in normal magnetic field has been considered.

Asymmetric Bimodal Exponential Power Distribution on the Real Line
Entropy, 2018 The asymmetric bimodal exponential power (ABEP) distribution is an extension of the generalized gamma distribution to the real line via adding two parameters that fit the shape of peakedness in bimodality on the real line.

BAYESIAN INFERENCE FOR THE HALF-NORMAL AND HALF-T DISTRIBUTIONS [PDF]
In this article we consider approaches to Bayesian inference for the half-normal and half-t distributions. We show that a generalized version of the normal-gamma distribution is conjugate to the half-normal likelihood and give the moments of this new ...

The International Trade Network: weighted network analysis and modelling
, 2008 Tools of the theory of critical phenomena, namely the scaling analysis and universality, are argued to be applicable to large complex web-like network structures. Using a detailed analysis of the real data of the International Trade Network we argue that

A Flexible Truncated (u,v)-Half-Normal Distribution: Properties, Estimation and Applications
MathematicsThis study introduces the truncated (u,v)-half-normal distribution, a novel probability model defined on the bounded interval (u,v), with parameters σ and b. This distribution is designed to model processes with restricted domains, ensuring realistic and
