We have two sets of scripts.

The first set of scripts using carry forward data.
1. 01_a_clean_cf_dataset.R
2. 02_a_regression.R
3. 03_a_tvmvar_cf.R
4. 04_a_classification_selfharm36m.R
5. 05_a_prediction_6mto6m.R
6. 06_a_prediction_6mto12m.R
7. 07_a_prediction_12mto6m.R
8. 08_a_prediction_12mto12m.R
9. 09_a_prediction_performance.R

The second set of scripts using imputed data.
1. 01_b_clean_cf_dataset.R
2. 02_b_regression.R
3. 03_b_tvmvar_cf.R
4. 04_b_classification_selfharm36m.R
5. 05_b_prediction_6mto6m.R
6. 06_b_prediction_6mto12m.R
7. 07_b_prediction_12mto6m.R
8. 08_b_prediction_12mto12m.R
9. 09_b_prediction_performance.R

Setup

Start the RStudio via longitudinal_selfharm.Rproj.

Usage

How to run the scripts

Step 1. Data Cleaning and Preprocessing
Step 2. Regression Models
Step 3. Time Varying Vector Autoregressive Model
Step 4. Classifying Indiviudals with and without Self-harm
Step 5. Future Self-harm Events Prediction (with 6m information to 6m prediction window)
Step 6. Future Self-harm Events Prediction (with 6m information to 12m prediction window)
Step 7. Future Self-harm Events Prediction (with 12m information to 6m prediction window)
Step 8. Future Self-harm Events Prediction (with 12m information to 12m prediction window)
Step 9. Visualization and Table for Prediction Models
