A New Logarithmic Tangent-U Family of Distributions with Reliability Analysis in Engineering Data

Computational Journal of Mathematical and Statistical Sciences
This article introduces a new family of distributions through the transformation involving tangent functions, referred to as the New Logarithmic Tangent-U family. The newly introduced family may be written as the NLT-U family of distribution. An overview

Thermodynamic analog of integrate-and-fire neuronal networks by maximum entropy modelling

Scientific Reports
Recent results have evidenced that spontaneous brain activity signals are organized in bursts with scale free features and long-range spatio-temporal correlations.

Investigation on the response of Fagus orientalis Lipsky to some environmental variables using beta function and its comparison with Gaussian function (Case study: Kheyrud forest research station( [PDF]

مجله جنگل ایران, 2013
The current study was done in Patom, Namkhaneh, Gorazbon, Chelir and Baharbon districts in Kheyrud forest. A stratified sampling method based on landform was used to locate 190 0.1 ha circular sample plots in beech dominated forests.

Modelling and Forecasting Financial Volatility with Realized GARCH Model: A Comparative Study of Skew-t Distributions Using GRG and MCMC Methods

Econometrics
Financial time-series data often exhibit statistically significant skewness and heavy tails, and numerous flexible distributions have been proposed to model them.

Crystal analysis of type $C$ Stanley symmetric functions

, 2017
Combining results of T.K. Lam and J. Stembridge, the type $C$ Stanley symmetric function $F_w^C(\mathbf{x})$, indexed by an element $w$ in the type $C$ Coxeter group, has a nonnegative integer expansion in terms of Schur functions.

Estimation of Peaked Densities Over the Interval [0,1] Using Two-Sided Power Distribution: Application to Lottery Experiments [PDF]

This paper deals with estimating peaked densities over the interval [0,1] using two-sided power distribution (Kotz, van Dorp, 2004). Such data were encountered in experiments determining certainty equivalents of lotteries (Kontek, 2010).

Diffusion hitting times and the Bell-shape

, 2015
Consider a generalized diffusion on R with speed measure m, in the natural scale. It is known that the conditional hitting times have a unimodal density function.

Computing semiparametric bounds on the expected payments of insurance instruments via column generation

, 2016
It has been recently shown that numerical semiparametric bounds on the expected payoff of fi- nancial or actuarial instruments can be computed using semidefinite programming. However, this approach has practical limitations. Here we use column generation,

Van Zwet ordering for Fechner asymmetry [PDF]

There are several procedures to construct a skewed distribution. One of these procedures splits the value of a parameter of scale for the two halfs of a symmetric distribution.
