Variable Selection Using aModified Gibbs Sampler Algorithm with Application on Rock Strength Dataset

Ghadeer J. M. Mahdi,
Othman M. Salih

Abstract: Variable selection is an essential and necessary task in the statistical modeling field. Several studies have triedto develop and standardize the process of variable selection, but it isdifficultto do so. The first question a researcher needs to ask himself/herself what are the most significant variables that should be used to describe a given dataset’s response. In thispaper, a new method for variable selection using Gibbs sampler techniqueshas beendeveloped.First, the model is defined, and the posterior dist… Show more

“…The formula w = (max − min)/q, is used for the purpose of calculating the interval width. Additionally, the phrases min + w, min + 2w, ..., and min + (q − 1)w are utilized to ascertain the limits of each individual interval [25,26].…”
