- Model the relationship between LIRRLowAdhesionDelays and AvgDelayPerLateTrain to understand delay causes.
- Forecast monthly service quality using the Month column and lagged performance indicators like NoofTrainsOver15MinsLate.
- Assess operational impacts by correlating NoofShortTrains with other delay metrics.
