Time Series Analysis for Data Quality Monitoring

: system selects events that contain potentially interesting objects for the CMS physics program. Then, the selected data are monitored for certification by experts. In this work, we establish correlations between the trigger rates and the monitoring histograms for the ZeroBias data set. The result shows that drops in the trigger rate may be related to turning on high voltage in the pixel detector. We find that a significant decrease in the trigger rates doesn't change statistical information which implies that physics is preserved when the trigger rates drop.
