Analyzing the Relationship Between Meteorological Elements and Criteria Atmospheric Pollutants in Tabriz Using Statistical Modeling [PDF]

open access: yesعلوم محیطی
Introduction: The rapid increase in population, growth of urbanization and industrialization in recent years, which is generally associated with an increase in demand and energy consumption, and as a result, an increase in pollutant emission sources, has

Comparative simulation study for model adequancy with binary response variable under multicollinearity – nonparametric approaches

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2017
Regression models used to explore the importance of several explanatory variables in estimation, classification and analytical tools play an efficient role for many data analysis.

gamboostLSS: An R Package for Model Building and Variable Selection in the GAMLSS Framework

open access: yesJournal of Statistical Software, 2016
Generalized additive models for location, scale and shape are a flexible class of regression models that allow to model multiple parameters of a distribution function, such as the mean and the standard deviation, simultaneously.

Data‐adaptive additive modeling

open access: yesStatistics in Medicine, 2018
In this paper, we consider fitting a flexible and interpretable additive regression model in a data‐rich setting. We wish to avoid pre‐specifying the functional form of the conditional association between each covariate and the response, while still retaining interpretability of the fitted functions.

Fused Lasso Additive Model [PDF]

open access: yesJournal of Computational and Graphical Statistics, 2016
We consider the problem of predicting an outcome variable using p covariates that are measured on n independent observations, in a setting in which additive, flexible, and interpretable fits are desired. We propose the fused lasso additive model (FLAM), in which each additive function is estimated to be piecewise constant with a small number of ...

Additive and non-additive genetic effects of humoral immune traits in Japanese quail

open access: yesJournal of Applied Poultry Research, 2022
SUMMARY: In breeding programs, using appropriate models to estimate the variance components with high accuracy is essential. Considering the non-additive genetic effects along with additive effects in evaluation analysis models can be effective in ...

Functional Generalized Additive Models [PDF]

open access: yesJournal of Computational and Graphical Statistics, 2014
We introduce the functional generalized additive model (FGAM), a novel regression model for association studies between a scalar response and a functional predictor. We model the link-transformed mean response as the integral with respect to t of F{X(t), t} where F(·,·) is an unknown regression function and X(t) is a functional covariate.

BayesX: Analyzing Bayesian Structural Additive Regression Models

open access: yesJournal of Statistical Software, 2005
There has been much recent interest in Bayesian inference for generalized additive and related models. The increasing popularity of Bayesian methods for these and other model classes is mainly caused by the introduction of Markov chain Monte Carlo (MCMC)

Estimation of parameters of autoregressive models with fractional differences in the presence of additive noise

open access: yesВестник Самарского университета: Естественнонаучная серия, 2023
For modeling in time series, models with fractional differences are widely used. The best known model is the ARFIMA (autoregressive fractionally integrated moving average) model.
