...as someone who has scoured and mined the NYC health department data (not to mention the review / grade pending period making the data even more worthless; i.e., most restaurants receive a hidden "C" at which point they display a "Grade Pending" sign then have a month to get their "A" at their reinspection and then most likely go back to their "C" ways --> to all those statisticians out there, which rating is the real one? the first one when they weren't expecting it or the one where they had a few weeks notice?
My hope and wish is that the letter grades determined by the score would be meaningfully correlated to the risk of food poisoning in the restaurant however there is little relationship between those things and that restaurants wouldn't have a chance to get a reinspection which clearly defeats the purpose of the test in the eyes of anyone with even the most minimal statistical/scientific education.
Instead of using google glass, the health department should reevaluate their methods of inspection and reinspection grading policy where part of their inspection relates to testing actual prepared food instead of seeing if a mouse or roach might have been on the floor (oftentimes they can just scurry in from the sidewalk and have zero impact on the food)
