On the Sequential Hierarchical Cognitive Diagnostic Model

open access: yesFrontiers in Psychology, 2020
Model data fit plays an important role in any statistical analysis, and the primary goal is to detect the preferred model based on certain criteria. Under the cognitive diagnostic assessment (CDA) framework, a family of sequential cognitive diagnostic ...

The Ethical Use of Fit Indices in Structural Equation Modeling: Recommendations for Psychologists

open access: yesFrontiers in Psychology, 2021
Fit indices provide helpful information for researchers to assess the fit of their structural equation models to their data. However, like many statistics and methods, researchers can misuse fit indices, which suggest the potential for questionable ...

Hypergraph modelling for geometric model fitting [PDF]

open access: yesPattern Recognition, 2016
In this paper, we propose a novel hypergraph based method (called HF) to fit and segment multi-structural data. The proposed HF formulates the geometric model fitting problem as a hypergraph partition problem based on a novel hypergraph model. In the hypergraph model, vertices represent data points and hyperedges denote model hypotheses. The hypergraph,

Fitting jump models

open access: yesAutomatica, 2018
We describe a new framework for fitting jump models to a sequence of data. The key idea is to alternate between minimizing a loss function to fit multiple model parameters, and minimizing a discrete loss function to determine which set of model parameters is active at each data point.

Fitting additive Poisson models [PDF]

open access: yesEpidemiologic Perspectives & Innovations, 2010
AbstractThis paper describes how to fit an additive Poisson model using standard software. It is illustrated with SAS code, but can be similarly used for other software packages.

A Meta-Analysis of Construct Reliability Indices and Measurement Model Fit Metrics

open access: yesMethodology, 2020
The present research examined the distributional properties of construct reliability indices and model fit metrics, explored relationships between and among the indices and metrics, and investigated variables influencing the relative magnitudes of the ...
