Results are shown for the nine outcomes that achieved a concentration of risk in the top-ventile of risk at least three times the expected value (i.e., 15.0%≤; see Table 3). Empty cells (--) indicate predictor categories that had no significant univariate associations or predictor categories that were not represented in a final model. Coefficients (odds ratios) for the final model predictors are available on request..
These columns report the percent of predictors within each predictor category with significant univariate associations with outcome (0.05 level, two-sided tests).
This ratio refers to the observed representation of the column predictor category divided by the expected representation of the column predictor category. For example, there was 1 socio-demographic variable selected among the 10 total final model variables for major physical perpetration - 10% representation. However 114 of all predictors were socio-demographic variables. – 14.8%. This ratio (10.0/14.8) is equal to 0.7.
This column reports the total proportion of all predictors with significant univariate associations with each outcome.
This column reports the total number of final model predictors selected by elastic net.
