• 00_Startup.R Downloads the necessary packages required to step through the rest of the R scripts
• 21_calculate_violation_matrix.R Performs matrix calculations on types of violations in the inspections data. This step is performed in a separate script as it takes some time.
• 22_calculate_heat_map_values.R Calculates heat maps for garbage, crime(burglary) and sanitation complaints data.
• 23_generate_model_dat.R Filter primary datsets, creates a basis for the model, creates features based on various data sets,attaches heat map, inspectors and weather and performs requisite merges to the basis model
• 30_glmnet_model.R The pre-calculated output from previous scripts is imported and used in the model built, trained and tested in this script. The main data set is indexed by time, and past data is used to independently build the model. The model is then applied to test data. Finally, this script also includes necessary code to evaluate the effectiveness of the City of Chicago’s data driven food inspections pilot.
