Mumbai Terror Attacks

A distributed terrorist attack began at about 10 PM local time in Mumbai, India, on November 26, 2008. The rampage ended after 60 hours, with hundreds dead or injured, and Mumbai's major centers and hotels including the Taj Mahal and the Oberoi in shambles.

Yahoo News reported that "It took just 10 young men armed with rifles and grenades to terrorize this city of 18 million and turn its postcard-perfect icons into battlefields until security forces ended one of the deadliest attacks in India's history early Saturday.

"The bloody rampage carried out by suspected Muslim militants at 10 sites across Mumbai, the nation's financial capital formerly known as Bombay, killed at least 195 people and wounded 295. Among the dead were 18 foreigners, including six Americans."

Although the standoff of security forces and terrorists continued for nearly three days, the GCP event was set for the 24 hours beginning at the time of the attacks. The data show a sharp drop for about two hours, which levels off and after about 14 hours assumes a positive trend with culmination at almost zero deviation. Chisquare is 86342.911 on 86400 df, for p = 0.554 and Z = -0.136.

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.
