Fred Bosick Apartment Fire
In the same spirit of exploration as for the Mike Cheponis fire,
examine the GCP data leading up to the shutdown of Fred Bosick's
egg due to a fire an a neighboring apartment.
Fred sent a note to let me know what had happened, and
suggested it might also be worth a look, and to add this
material to the exploratory database.
The last data packet from Egg 2222 arived at 20:05 on the 22nd. For the exploratory analysis, I took the whole day up to 20:05, plotting the cumulative deviation of scores for all eggs (red) for egg 2222 alone (green), and the difference. The first figure shows this, and is actually a striking picture. The data from all eggs has a couple of periods of persistent large deviation, including a strong negative trend beginning about an hour before Fred's egg lost power. The second figure shows this period separately, and displays more clearly the extreme departure.
It is tempting to interpret this picture as showing a response to the emergency situation, but when we look at egg 2222 alone, there is no obvious trend -- the data show a classic random walk. As we so often must observe, there is much to learn before we can draw conclusions from the EGG data.
