Interpreting the Ising Model: The Input Matters
Jonas Haslbeck, Sacha Epskamp, Maarten Marsman +1
The Ising model is a model for pairwise interactions between binary variables that has become popular in the psychological sciences. It has been first introduced as a theoretical m…
The Gaussian Graphical Model in Cross-sectional and Time-series Data
Sacha Epskamp, Lourens J. Waldorp, René Mõttus +1
We discuss the Gaussian graphical model (GGM; an undirected network of partial correlation coefficients) and detail its utility as an exploratory data analysis tool. The GGM shows…
Network Psychometrics
Sacha Epskamp, Gunter K. J. Maris, Lourens J. Waldorp +1
This chapter provides a general introduction of network modeling in psychometrics. The chapter starts with an introduction to the statistical model formulation of pairwise Markov r…
A Tutorial on Regularized Partial Correlation Networks
Sacha Epskamp, Eiko I. Fried
Recent years have seen an emergence of network modeling applied to moods, attitudes, and problems in the realm of psychology. In this framework, psychological variables are underst…
Brief Report on Estimating Regularized Gaussian Networks from Continuous and Ordinal Data
Sacha Epskamp
In recent literature, the Gaussian Graphical model (GGM; Lauritzen, 1996),a network of partial correlation coefficients, has been used to capture potential dynamic relationships be…
Generalized Network Psychometrics: Combining Network and Latent Variable Models
Sacha Epskamp, Mijke Rhemtulla, Denny Borsboom
We introduce the network model as a formal psychometric model, conceptualizing the covariance between psychometric indicators as resulting from pairwise interactions between observ…
Exploratory graph analysis: a new approach for estimating the number of dimensions in psychological research
Hudson F. Golino, Sacha Epskamp
The estimation of the correct number of dimensions is a long-standing problem in psychometrics. Several methods have been proposed, such as parallel analysis (PA), Kaiser-Guttman's…
Estimating Psychological Networks and their Accuracy: A Tutorial Paper
