We first compared the loadings of each indicator across the common factor, EXT-ARF and BD-SUB models. The loadings were relatively stable (Figure 3A), indicating that each indicator had a similar loading on its respective factor in each model. We next ran a series of analyses to test the sensitivity of factors to their indicators by dropping one indicator from the model at a time. Figure 3B,C shows the range of factor loadings and standard errors of an individual indicator when each other indicator was dropped from the model one at a time. Overall, factors were not very sensitive to their indicators, as evidenced by the low variability of loadings (Figure 3B) and their standard errors (Figure 3C). We observed the most variability for the standard errors of SUDs in the EXT-ARF model. Factor correlations in the EXT-ARF and BD-SUB models were also stable, ranging from 0.78 to 0.94 and 0.84 to 0.90, respectively.
