Abstract

We extend the work of Koehler, Skvortsov, and Vos (2013) to measure cross-device online audiences.
The method performs demographic corrections in the usual way device-by-device. A new method
that converts cross-device cookie counts to user counts is introduced. We provide practical recipes
for fitting this transformation function and then demonstrate its use using online panel data from
Japan.
