Fig. 10: Comparison between ResIN and MDS.
From: Response Item Network (ResIN): A network-based approach to explore attitude systems
a Placing the nodes in the 2-dimensional space according to MDS. Notice how the structure is curved, suggesting a second dimension even if IRT has used only 1. b The same data visualized with ResIN showing no curvature. c Scatterplot of the relationship between ResIN (blue) and MDS (orange) compared to IRT. d Scatterplot showing the position of the nodes in ResIN when re-running the force-directed algorithm. Closeness to the diagonal shows very minimal variations.
