Geometric goodness of fit measure to detect patterns in data point clouds

期刊: COMPUTATIONAL STATISTICS, 2023; 38 (3)

In this work, we derive a geometric goodness-of-fit index similar to R-2 using geometric data analysis techniques. We build the alpha shape complex fr......

A semi-parametric approach to feature selection in high-dimensional linear regression models

期刊: COMPUTATIONAL STATISTICS, 2023; 38 (2)

We propose a novel semi-parametric approach to feature selection in high-dimensional linear regression models. This sequential procedure is robust to ......

Solving linear Bayesian inverse problems using a fractional total variation-Gaussian (FTG) prior and transport map

期刊: COMPUTATIONAL STATISTICS, 2023; ()

The Bayesian inference is widely used in many scientific and engineering problems, especially in the linear inverse problems in infinite-dimensional s......

Computing T-optimal designs via nested semi-infinite programming and twofold adaptive discretization

期刊: COMPUTATIONAL STATISTICS, 2023; ()

Modelling real processes often results in several suitable models. In order to be able to distinguish, or discriminate, which model best represents a ......

Wavelet-based Bayesian approximate kernel method for high-dimensional data analysis

期刊: COMPUTATIONAL STATISTICS, 2023; ()

Kernel methods are often used for nonlinear regression and classification in statistics and machine learning because they are computationally cheap an......

Bayesian analysis of spherically parameterized dynamic multivariate stochastic volatility models

期刊: COMPUTATIONAL STATISTICS, 2023; 38 (2)

In this paper, we propose multivariate stochastic volatility models with a spherical parameterization of a Cholesky decomposition to make a time-depen......

A simple portmanteau test with data-driven truncation point

期刊: COMPUTATIONAL STATISTICS, 2023; ()

Time series forecasting is an important application of many statistical methods. When it is appropriate to assume that the data may be projected towar......

An exploration of National Weather Service daily forecasts using R Shiny

期刊: COMPUTATIONAL STATISTICS, 2023; 38 (3)

Weather forecasts often affect daily lives of billions of people globally. Accurate forecasts can help combat and effectively mitigate damage caused b......

Bayesian flexible beta regression model with functional covariate

期刊: COMPUTATIONAL STATISTICS, 2023; 38 (2)

Standard parametric regression models are unsuitable when the aim is to predict a bounded continuous response, such as a proportion/percentage or a ra......

A hybrid deterministic-deterministic approach for high-dimensional Bayesian variable selection with a default prior

期刊: COMPUTATIONAL STATISTICS, 2023; ()

Identifying relevant variables among numerous potential predictors has been of primary interest in modern regression analysis. While stochastic search......

House quality index construction and rent prediction in New York City with interactive visualization and product design

期刊: COMPUTATIONAL STATISTICS, 2023; ()

Housing is of primary importance for immigrants in New York City. This study analyzed the housing conditions of and price changes for residents in New......

Spatial correlation in weather forecast accuracy: a functional time series approach

期刊: COMPUTATIONAL STATISTICS, 2023; 38 (3)

A functional time series approach is proposed for investigating spatial correlation in daily maximum temperature forecast errors for 111 cities spread......

Generative models and Bayesian inversion using Laplace approximation

期刊: COMPUTATIONAL STATISTICS, 2023; ()

The Bayesian approach to solving inverse problems relies on the choice of a prior. This critical ingredient allows expert knowledge or physical constr......

Multi-step estimators and shrinkage effect in time series models

期刊: COMPUTATIONAL STATISTICS, 2023; ()

Many modern statistical models are used for both insight and prediction when applied to data. When models are used for prediction one should optimise ......

Inference for a constant-stress model under progressive type-II censored data from the truncated normal distribution

期刊: COMPUTATIONAL STATISTICS, 2023; ()

In this study, constant-stress accelerated life testing has been investigated using type-II censoring of failure data from a truncated normal distribu......
