Common Evening and Common Daytime Derivation

This paper discusses the methodology of how we use our mobile data to look back over 2 months and do a frequency clustering to determine the CEL and CDLs for devices.

The UberMedia user database is developed by associating a user device ID (Apple IDFA or Android AAID) with a Common Evening Location (CEL) and a Common Daytime Location (CDL), then associating each of those locations with various geographic districts. District assignments always includes the country. In several countries, various additional districts are available, including the state, postal code and census region

When to Send: When someone asks you how we determine our CEL and CDLs, or what hours we use, or what information comes along with the CEL/CDL.
