Table 3 CPC for Twitter-based estimates using different time-based heuristics, for both hard and soft assignment techniques. Brackets contain bootstrapped 95% confidence intervals. The restricted day only considers tweets from 10:00-15:00 when calculating the work location, and tweets from 20:00-23:00 when calculating the home location
