Stochastic Volatility Effects on Correlated Log-Normal Random Variables

open access: yesAdvances in Mathematical Physics, 2017
The transition density function plays an important role in understanding and explaining the dynamics of the stochastic process. In this paper, we incorporate an ergodic process displaying fast moving fluctuation into constant volatility models to express

Fragile extended phases in the log-normal Rosenzweig-Porter model

open access: yesPhysical Review Research, 2020
In this paper, we suggest an extension of the Rosenzweig-Porter (RP) model, the LN-RP model, in which the off-diagonal matrix elements have a wide, log-normal distribution.

LogConcDEAD: An R Package for Maximum Likelihood Estimation of a Multivariate Log-Concave Density [PDF]

open access: yes
In this article we introduce the R package LogConcDEAD (Log-concave density estimation in arbitrary dimensions). Its main function is to compute the nonparametric maximum likelihood estimator of a log-concave density.

Log-Normal Waiting Time Widths Characterize Dynamics

open access: yesThe Open Journal of Astrophysics
Many astronomical phenomena, including Fast Radio Bursts and Soft Gamma Repeaters, consist of brief distinct aperiodic events. The intervals between these events vary randomly, but there are periods of greater activity, with shorter mean intervals, and ...
