A robust and efficient stepwise regression method for building sparse polynomial chaos expansions Vrije Universiteit Brussel
Polynomial Chaos (PC) expansions are widely used in various engineering fields for quantifying uncertainties arising from uncertain parameters. The computational cost of classical PC solution schemes is unaffordable as the number of deterministic simulations to be calculated grows dramatically with the number of stochastic dimension. This considerably restricts the practical use of PC at the industrial level. A common approach to address such ...
Cross-validated stepwise regression for identification of novel non-nucleoside reverse transcriptase inhibitor resistance associated mutations Universiteit Hasselt KU Leuven
Background: Linear regression models are used to quantitatively predict drug resistance, the phenotype, from the HIV-1 viral genotype. As new antiretroviral drugs become available, new resistance pathways emerge and the number of resistance associated mutations continues to increase. To accurately identify which drug options are left, the main goal of the modeling has been to maximize predictivity and not interpretability. However, we originally ...

Modeling soil moisture from multisource data by stepwise multilinear regression: An application to the Chinese Loess Plateau Vrije Universiteit Brussel
This study aims to integrate multisource data to model the relative soil moisture (RSM) over the Chinese Loess Plateau in 2017 by stepwise multilinear regression (SMLR) in order to improve the spatial coverage of our previously published RSM. First, 34 candidate variables (12 quantitative and 22 dummy variables) from the Moderate Resolution Imaging Spectroradiometer (MODIS) and topographic, soil properties, and meteorological data were ...
Input variable selection with greedy stepwise search algorithm for analysing the probability of fish occurrence : a case study for Alburnoides mossulensis in the Gamasiab River, Iran Universiteit Gent
Input variable selection using data-driven combined with statistical methods have received more attention to analyse the probability of freshwater organisms' occurrence. Eight different sampling sites (from the source to the mouth of Gamasiab River basin, Iran) were considered to study the occurrence of Alburnoides mossulensis during one year study period (2008-2009). A set of river characteristics together with abundance of target fish (based ...
A stepwise approach to move from a cleavage-stage to a blastocyst-stage transfer policy for all patients in the IVF clinic Universiteit Gent
STUDY QUESTION: Is a stepwise change management approach an efficacious method to move from a Day 3 transfer policy to a Day 5 transfer policy for all patients in an IVF program? SUMMARY ANSWER: A stepwise change from a Day 3 to a Day 5 transfer policy maintained the live birth rates per oocyte collection cycle (OCC) of the IVF program, with increased single embryo transfer (SET) and reduction of twin pregnancies. WHAT IS KNOWN ALREADY Evidence ...
Impact of stepwise introduction of smoke-free legislation on population rates of acute myocardial infarction deaths in Flanders, Belgium Universiteit Hasselt KU Leuven
Objective Many studies demonstrated a decline in hospital admissions for cardiovascular diseases after the implementation of a smoking ban, but evidence for reductions in cardiovascular mortality is more limited. In Belgium, smoke-free legislation was implemented in different phases. Public places and most workplaces became smoke-free in January 2006, whereas the legislative ban on smoking in restaurants was introduced in January 2007. These ...
Impact of a stepwise introduction of smoke-free legislation on the rate of preterm births: analysis of routinely collected birth data Universiteit Hasselt KU Leuven
Objective To investigate the incidence of preterm delivery in the Belgian population after implementation of smoke-free legislation in three phases (in public places and most workplaces January 2006, in restaurants January 2007, and in bars serving food January 2010). Design Logistic regression analyses on routinely collected birth data from January 2002 to December 2011. Setting Flanders, Belgium. Population All live born singleton births ...
