From our model results, the strongest positive predictors were "Have you thought about suicide - Yes" (V6301_YES), "Have you made a suicide plan? - Yes (V6305_YES), and "Irritability - Very" (V5112_VERY). This was expected based on the subject matter of these variables.
The strongest negative predictors were both indicators of highly educated persons, "EDCAT_13-15 Years" and "EDCAT_16+ Years".
For future use of the model, a user would need to select their threshold to use for recall of the classifier. We saw that with a threshold of -2, we could reach 82% recall with a precision of 39%. Essentially, increasing recall will decrease precision. Additional work should be performed to optimize the threshold for future use.
