more data exhaust

UBS is incorporating satellite data in its reports on Wal-Mart. "By counting the cars in Wal-Mart’s parking lots month in and month out, Remote Sensing Metrics analysts were able to get a fix on the company’s customer flow. From there, they worked up a mathematical regression to come up with a prediction of the company’s quarterly revenue each month." UBS didn't comment on whether they're also including keystroke data from Stephen Wolfram in their analysis.
