Parameters that were not instrument or method dependent were then systematically varied, resulting in as many data sets as the number of times the parameter settings were changed.
Many data sets show this.
Furthermore, many data sets that do end up being published are not relevant.
Dr. Bryan Sykes, a human geneticist at Oxford University, said his laboratory had run similar tests on many data sets but had not found evidence of recombination.
Princeton's Ed Felten – formerly of the US Federal Trade Commission –said: "A decade of computer science research shows that many data sets can be re-identified.
But all data will have some utility – and a substantial amount of data use will exist under the tail of the distribution with many data sets used by only a few.
Meanwhile, the extent and quality of locally-gathered data is usually linked to a country's income, and often needs pulling together: "Brazil is a good example of having good data, but it is scattered across many data sets," says Prasad.
The crown jewels will always be kept locked up but many data sets will increasingly be made available for businesses to combine and turn into new services to improve cities, to shorten commutes and to improve workforces.
How many data sets have you incorporated into your story?
Many data sets, however, do not record hourly rain intensities but qualitative intensities such as light, moderate, or heavy.
However, many data sets contain ordering information helpful for revealing patterns or for locating particular objects in hierarchies [6].
