[…] the norm score of 123., we estimated a sparse gaussian network based on the polychoric correlations between the responses to the scl-90-r items using the glasso-method implemented in the r-package qgraph. glasso estimates partial correlations between each pair of variables conditioning on all other variables. as such, we can interpret the network as depicting conditional dependence relations: […]

[…] strength and closeness scores allows researchers to assess the potential impact of a targeted treatment regimen. centrality plots and calculation of centrality measures were performed with the qgraph package [] in the r scripting language []. network plots were produced with gephi []., finally, we compute within patient community symptom clusters using random walk community detection, […]

[…] never to every day, or nearly every day were used to derive a binary indicator coded as (0) no self-harm, (1) self-harm., correlations between 116 items used in bifactor analysis were computed in r qgraph and visualised as a network plot (see the additional file , fig. ). confirmatory factor analyses with mplus 7.4 of the original questionnaires showed moderate to low fit indices of the models; […]

[…] network structure across the four time points; and 4) finally, we evaluated the robustness of our findings by exploring the accuracy of edge weights and centrality indices., we used the r-package qgraph to estimate and visualize all networks [], and followed state-of-the-art procedures to estimate regularized partial correlation networks using the gaussian graphical model (ggm) for each time […]

[…] dependent on the activation of its neighbouring nodes; for dichotomous variables) fitted using elasso have been developed. these network estimation methods are readily implemented in the r package qgraph and isingfit (https://cran.r-project.org/web/packages/isingfit/index.html). having been combined with graph theory metrics,, hierarchical and segregated relationships among […]
