Baseline Methods for the Parameter Estimation of the Generalized Pareto Distribution

open access: yesEntropy, 2022
In the parameter estimation of limit extreme value distributions, most employed methods only use some of the available data. Using the peaks-over-threshold method for Generalized Pareto Distribution (GPD), only the observations above a certain threshold ...

Metropolis-Hastings algorithm for extracting periodic gravitational wave signals from laser interferometric detector data [PDF]

open access: yes, 2004
The Markov chain Monte Carlo methods offer practical procedures for detecting signals characterized by a large number of parameters and under conditions of low signal-to-noise ratio.

Bayesian Adaptive Lasso for the Partial Functional Linear Spatial Autoregressive Model

open access: yesJournal of Mathematics, 2022
This study introduces a partial functional linear spatial autoregressive model which can explore the relationship between a scalar spatially dependent response variable and predictive variables containing both multiple scalar covariates and a functional ...

Does waste-recycling really improve Metropolis-Hastings Monte Carlo algorithm? [PDF]

open access: yes, 2009
The Metropolis Hastings algorithm and its multi-proposal extensions are aimed at the computation of the expectation $$ of a function $f$ under a probability measure $\pi$ difficult to simulate.

Adaptive independent Metropolis--Hastings

open access: yes, 2009
We propose an adaptive independent Metropolis--Hastings algorithm with the ability to learn from all previous proposals in the chain except the current location. It is an extension of the independent Metropolis--Hastings algorithm.

Hidden Markov Quantile Models With Trends for Analysing Air Temperature Data

open access: yesInternational Journal of Climatology, EarlyView.
There is the question of whether climate change, expressed by time‐trends in temperature, is of a heterogeneous nature or not. Here, the time‐trend heterogeneity argument has been investigated using Hidden Markov (HM) quantile time‐trends models in temperature time series.

Lung Cancer Pathological Image Analysis Using a Hidden Potts Model

open access: yesCancer Informatics, 2017
Nowadays, many biological data are acquired via images. In this article, we study the pathological images scanned from 205 patients with lung cancer with the goal to find out the relationship between the survival time and the spatial distribution of ...

Beyond our backyard: Unravelling how social‐ecological fit drives the formation of inter‐regional collaborative networks for water governance in the Yellow River Basin

open access: yesPeople and Nature, EarlyView.
Abstract The societal and biophysical permeability across human‐demarcated jurisdictions within watersheds necessitates collaboration among administrative regions. The effectiveness of such collaboration is partly determined by the degree to which institutional arrangements align with underlying social and ecological interdependencies, a concept ...

Bayesian Estimation for the Centered Parameterization of the Skew-Normal Distribution

open access: yesRevista Colombiana de Estadística, 2017
The skew-normal (SN) distribution is a generalization of the normal distribution, where a shape parameter is added to adopt skewed forms. The SN distribution has some of the properties of a univariate normal distribution, which makes it very attractive ...
