An MCMC Fitting Method for Triaxial Dark Matter Haloes [PDF]

, 2008
Measuring the 3D distribution of mass on galaxy cluster scales is a crucial test of the LCDM model, providing constraints on the behaviour of dark matter. Recent work investigating mass distributions of individual galaxy clusters (e.g.

Analysis of stress-strength reliability with m-step strength levels under type I censoring and Gompertz distribution

AIMS Mathematics
Because of modern technology, product reliability has increased, making it more challenging to evaluate products in real-world settings and raising the cost of gathering sufficient data about a product's lifetime.

Practical guidelines for Bayesian phylogenetic inference using Markov Chain Monte Carlo (MCMC) [version 1; peer review: 2 approved, 1 approved with reservations]

Open Research Europe, 2023
Phylogenetic estimation is, and has always been, a complex endeavor. Estimating a phylogenetic tree involves evaluating many possible solutions and possible evolutionary histories that could explain a set of observed data, typically by using a model of ...

A framework for adaptive MCMC targeting multimodal distributions [PDF]

Annals of Statistics, 2018
We propose a new Monte Carlo method for sampling from multimodal distributions. The idea of this technique is based on splitting the task into two: finding the modes of a target distribution $\pi$ and sampling, given the knowledge of the locations of the
