That is because when examining extreme events, many simulations are needed to generate a robust result.
"It is a robust result," said Dr. Richard J. Mayer of the Dana-Farber Cancer Institute in Boston.
That may sound like a pretty robust result, but it falls considerably short of particle physicists' preferred benchmark.
But the event being analysed is an extreme one, so tens of thousands of re-runs are likely to be needed to deliver a statistically robust result.
However, in reality, the increase in deep ocean heat accumulation is a robust result also observed in data sets that do not include reanalysis.
Early treatments there were called "Hail Mary fracks" because geologists and engineers would just drill a well, pump in frack fluid and pray for a robust result.
The results so far are shown in the video below but the University of Oxford researchers expect to need tens of thousands of model runs to produce a statistically robust result.
Two weeks out "Green Lantern" was showing strong interest from men of all ages and solid interest among young women, leading to rough predictions of an opening weekend in the $50 million range, a robust result for a nonsequel.
Indeed, despite the negative media coverage of the film, box office forecasters say the picture is on track to sell between $60 million and $70 million in tickets by Monday — a very robust result.
That surprisingly robust result, attributed largely to an aggressive online marketing campaign, reinforces Paramount's status as the current kingpin of the horror genre, which has sagged of late with the exception of the studio's "Paranormal Activity" franchise.
The robust result for "Shutter Island" validates Paramount's decision in August to abandon the film's initial release date of Oct. 2, though a marketing campaign was already well under way.
