First hitting time models for the generalized inverse Gaussian distribution

open access: yesStochastic Processes and their Applications, 1978
AbstractAny generalized inverse Gaussian distribution with a non-positive power parameter is shown to be the distribution of the first hitting time of level 0 for each of a variety of time-homogeneous diffusions on the interval [0, ∞). The infinite divisibility of the generalized inverse Gaussian distributions is a simple consequence of this and an ...

A Generator for Generalized Inverse Gaussian Distributions

open access: yes, 2022
We propose a new generator for the generalized inverse Gaussian (GIG) distribution by decomposing the density of GIG into two components. The first component is a truncated inverse Gamma density, in order to sample from which we improve the traditional inverse CDF method.

Gibbs Sampler for Matrix Generalized Inverse Gaussian Distributions

open access: yesJournal of Computational and Graphical Statistics, 2023
Sampling from matrix generalized inverse Gaussian (MGIG) distributions is required in Markov Chain Monte Carlo (MCMC) algorithms for a variety of statistical models. However, an efficient sampling scheme for the MGIG distributions has not been fully developed.

A Monte Carlo Approach to Bitcoin Price Prediction with Fractional Ornstein–Uhlenbeck Lévy Process

open access: yesForecasting, 2022
Since its inception in 2009, Bitcoin has increasingly gained main stream attention from the general population to institutional investors. Several models, from GARCH type to jump-diffusion type, have been developed to dynamically capture the price ...

Sampling High-Dimensional Gaussian Distributions for General Linear Inverse Problems [PDF]

open access: yesIEEE Signal Processing Letters, 2012
This paper is devoted to the problem of sampling Gaussian distributions in high dimension. Solutions exist for two specific structures of inverse covariance: sparse and circulant. The proposed algorithm is valid in a more general case especially as it emerges in linear inverse problems as well as in some hierarchical or latent Gaussian models.

Tsallis Entropy, Likelihood, and the Robust Seismic Inversion

open access: yesEntropy, 2020
The nonextensive statistical mechanics proposed by Tsallis have been successfully used to model and analyze many complex phenomena. Here, we study the role of the generalized Tsallis statistics on the inverse problem theory.

Improved parameter estimators for the flexible extended skew-t model with extensive simulations, applications and volatility modeling

open access: yesScientific African, 2023
This study introduces a new conditional innovation density called the generalized odd generalized exponentiated skew-t (GOGEST) distribution for the generalized autoregressive conditional heteroscedasticity (GARCH) volatility models.
