Summary

Description
English: This graph belongs to a study to determine whether the entropy of UserAgent fields in a test data set (navigationtiming) can be used in combination with an anomaly detection process to detect data quality issues. The 3 UserAgent fields combined to calculate this entropy value are: os_family, browser_family and device_family.
