The Manny Pacquiao Effect

Jorge Espinosa wrote to suggest that we should consider the effect on the GCP of the Philipino boxer Manny Pacquiao.

He literally shuts down the entire nation of the philipines whenever he fights. There are zero crimes the day he fights, businesses shut down, and come fight time, there can be upwards of 200 people gathered around 15 inch tv's, on the streets! EVERYONE sees it, and everyone has their attention and positive vibes on their fellow countryman for at least 1 hours or until the event ends.

Plus he's a different type of athlete; an actual congressman, and gives back to his people as opposed to other famous boxers who just want to make a big paycheck to inflate their wallets. It's no wonder he shuts down his nation, literally, when he performs.

I think this athlete is influential and charismatic enough to have drawn enough worldwide buzz in his past bouts.. The charisma thing, is an understatement, I mean, I can't think of any active world-class athletes who are currently congressmen in their country.

His last bout was on May 7th, 2011. The event started at 9:00pm ET with two opening undecard bouts leading up to the main event. He actually stepped into the ring between 11:15-11:45pm ET. I don't have exact times at the moment (I can find out though, just need a day). The other bout before this one was on Nov. 13th 2010 with pretty much the same time and sequence of undercard bouts/main-event. and before that, March 13th 2010, and before that, Nov. 14th 2009. and one in particualar vs Oscar de la Hoya, (his "break-through fight" you could call it) on Dec 6, 2008.

This sounded promising, so I set a consistent GCP event for each of 5 fights, using 11 pm to 2 am ET to get a bit of the pre-fight flavor and then the bout and some post bout time. The accumulation is shown in the first figure, with the individual bouts following.

The individual graphs show how this accumulation comes about. Four of the five fights correspond to a positive deviation in the GCP data, and two of those are quite significant, with odds less than 1 in 100. The fight dates are shown in the title, in the format YYMMDD.

It is important to keep in mind that we have only a tiny statistical effect, so that it is always hard to distinguish signal from noise. This means that every "success" might be largely driven by chance, and every "null" might include a real signal overwhelmed by noise. In the long run, a real effect can be identified only by patiently accumulating replications of similar analyses.
