The envelope model is a new paradigm to address estimation and prediction in multivariate analysis. Using sufficient dimension reduction techniques, it has the potential achieve substantial efficiency gains compared standard models. This was first introduced by [Statist. Sinica 20 (2010) 927–960] for linear regression, since been adapted many other contexts. However, Bayesian approach analyzing models not yet investigated literature. In this paper, we develop comprehensive framework...
In recent years, a large variety of continuous shrinkage priors have been developed for Bayesian analysis the standard linear regression model in high dimensional settings. We consider two such priors, Dirichlet-Laplace prior (developed Bhattacharya et al. (2013)), and Normal-Gamma (Griffin Brown, 2010)). For both Gibbs sampling Markov chains to generate approximate samples from corresponding posterior distributions. show by using drift minorization based that aforementioned models are...
Abstract Background Prediction and classification algorithms are commonly used in clinical research for identifying patients susceptible to conditions such as diabetes, colon cancer, Alzheimer’s disease. Developing accurate prediction methods benefits personalized medicine. Building an excellent predictive model involves selecting the features that most significantly associated with outcome. These can include several biological demographic characteristics, genomic biomarkers health history....
We introduce a new family of probability distributions that we call the Modified-Half-Normal distributions. It is supported on positive part real line with its density proportional to function x↦xα−1 exp (−βx2+γx)I(x>0),α>0,β>0,γ∈R. explore number properties including showing fact normalizing constant and moments distribution can be represented in terms Fox-Wright function. demonstrate relevance by connection Bayesian statistical methods appearing from multiple areas research such as Binary...
The data augmentation (DA) approach to approximate sampling from an intractable probability density fX is based on the construction of a joint density, fX, Y, whose conditional densities, fX|Y and fY|X, can be straightforwardly sampled. However, many applications DA algorithm do not fall in this “single-block” setup. In these applications, X partitioned into two components, = (U, V), such way that it easy sample fU|V, fV|U, Y. We refer alternative version DA, which effectively three-variable...

Directional data emerges in a wide array of applications, ranging from atmospheric sciences to medical imaging. Modeling such data, however, poses unique challenges by virtue their being constrained non-Euclidean spaces like manifolds. Here, we present unified Bayesian framework for inference on the Stiefel manifold using Matrix Langevin distribution. Specifically, propose novel family conjugate priors and establish number theoretical properties relevant statistical inference. Conjugacy...
Recent advances in neuroimaging technologies have provided opportunities to acquire brain images of different modalities for studying human organization from both functional and structural perspectives. Analysis derived various involves some common goals such as dimension reduction, denoising, feature extraction. However, since these vastly data characteristics, the current analysis is usually performed using distinct analytical tools that are only suitable a specific imaging modality. In...
The Horseshoe is a widely used and popular continuous shrinkage prior for high-dimensional Bayesian linear regression. Recently, regularized versions of the have also been introduced in literature. Various Gibbs sampling Markov chains developed literature to generate approximate samples from corresponding intractable posterior densities. Establishing geometric ergodicity these provides crucial technical justification accuracy asymptotic standard errors chain based estimates quantities. In...

It can be challenging to perform an integrative statistical analysis of multi-view high-dimensional data acquired from different experiments on each subject who participated in a joint study. Canonical Correlation Analysis (CCA) is procedure for identifying relationships between such sets. In that context, Structured Sparse CCA (ScSCCA) rapidly emerging methodological area aims robust modeling the interrelations modalities by assuming corresponding directional vectors sparse. Although it...
Observational data, such as electronic clinical records and claims can prove invaluable for evaluating the Average Treatment Effect (ATE) supporting decision-making, provided they are employed correctly. The Inverse Probability of Weighting (IPTW) method, based on propensity scores, has demonstrated remarkable efficacy in estimating ATE, assuming that assumptions exchangeability, consistency, positivity met. Directed Acyclic Graphs (DAGs) offer a practical approach to assess exchangeability...
Abstract Background Count data regression modeling has received much attention in several science fields which the Poisson, Negative binomial, and Zero-Inflated models are some of primary techniques. binomial is applied to count variables, usually when they over-dispersed. A Poisson distribution also utilized for counting where mean equal variance. This situation often unrealistic since counts will have a variance that not its mean. Modeling it as distributed leads ignoring under- or...
