Signature 3

The low-rank spatial signature shown above is sensitive to holidays. The blue lines in these plots correspond to (from top left) Monday July 4th 2011 (Independence Day), Monday October 31 2011 (Halloween), and Thursday November 24th 2011 (Thanksgiving). The blue line is the signature weight for the day of interest, the green lines are the signature weights for the remaining days of the year, and the red line is the average of the signature weights for the year.
