New developments in factor score regression : fit indices and a model comparison test Ghent University
A statistical test to reject the structural interpretation of a latent factor model Ghent University
Factor score regression with social relations model components : a case study exploring antecedents and consequences of perceived support in families Ghent University
The family social relations model (SRM) is applied to identify the sources of variance in interpersonal dispositions in families, but the antecedents or consequences of those sources are rarely investigated. Simultaneous modeling of the SRM with antecedents or consequences using structural equation modeling (SEM) allows to do so, but may become computationally prohibitive in small samples. We therefore consider two factor score regression (FSR) ...
A statistical basis for harmonization of thyroid stimulating hormone immunoassays using a robust factor analysis model Ghent University
A misspecification test for the higher order co-moments of the factor model Vrije Universiteit Brussel KU Leuven Ghent University
The traditional estimation of higher order co-moments of non-normal random variables by the sample analog of the expectation faces a curse of dimensionality, as the number of parameters increases steeply when the dimension increases. Imposing a factor structure on the process solves this problem; however, it leads to the challenging task of selecting an appropriate factor model. This paper contributes by proposing a test that exploits the ...
A combined multilevel factor analysis and covariance regression model with mixed effects in the mean and variance structure KU Leuven
Li et al developed a multilevel covariance regression (MCR) model as an extension of the covariance regression model of Hoff and Niu. This model assumes a hierarchical structure for the mean and the covariance matrix. Here, we propose the combined multilevel factor analysis and covariance regression model in a Bayesian framework, simultaneously modeling the MCR model and a multilevel factor analysis (MFA) model. The proposed model replaces the ...
Alginate sulfate-nanoparticles loaded with hepatocyte growth factor and insulin-like growth factor-1 improve left ventricular repair in a porcine model of myocardial ischemia reperfusion injury KU Leuven
Nanomedicine offers great potential for the treatment of cardiovascular disease and particulate systems have the capacity to markedly improve bioavailability of therapeutics. The delivery of pro-angiogenic hepatocyte growth factor (HGF) and pro-survival and pro-myogenic insulin-like growth factor (IGF-1) encapsulated in Alginate-Sulfate nanoparticles (AlgS-NP) might improve left ventricular (LV) functional recovery after myocardial infarction ...
Validation of the harmonized partial factor method for design and assessment of concrete structures as proposed for fib model code 2020 Ghent University
When considering the assessment of concrete structures, a consistent approach to assess the safety level of existing structures in an objective and well-founded way is currently still lacking in practice. As such, fib TG3.1 has developed proposals for the quantification of adjusted partial factors for the assessment of existing structures and has harmonized these proposals with partial factors for design. This resulted in a set of equations and ...
