Both goodness-of-fit estimates were highly replicable across the discovery and replication groups and suggested that a three-dimensional solution was optimal. Stress was plotted as a function of the number of estimated dimensions. Lower stress indicates better fit. The scree plot of normalized stress had an “elbow” when dimensionality was at 3, since further addition of dimensions did not substantially reduce normalized stress. Dashed line indicates normalized stress of 0.05. DAF was plotted as a function of the number of estimated dimensions. Higher DAF indicates better fit. Dashed line indicates DAF of 0.98.
