Derrière les records chinois La Chine semble battre tous les records : première exportatrice mondiale (devant l’Allemagne), première vendeuse d’automobiles (devant les Etats-Unis), première croissance économique (entre 8,5 et 9 %)… Les autorités chinoises s’esbaudissent sur cette année 2009 qui avait mal commencé et se termine en apothéose. La plupart des économistes et financiers occidentaux applaudissent eux aussi, d’autant plus fort que beaucoup avaient pronostiqué l’incapacité chinoise à relancer sa machine. D’autres, au contraire, s’alarment devant une « économie prédatrice » qui a réussi à vendre toujours plus sur des marchés toujours moins dynamiques... et continuent à prévoir un krach dans les prochains mois. Comment s’y retrouver ? Selon les statistiques officielles chinoises, les exportations ont atteint 1 200 milliards de dollars (930 milliards d’euros) en 2009, portant l’excédent commercial à 196 milliards de dollars (135 milliards d’euros). En attendant, Pékin accumule des excédents importants.

Prediction market People who buy low and sell high are rewarded for improving the market prediction, while those who buy high and sell low are punished for degrading the market prediction. Evidence so far suggests that prediction markets are at least as accurate as other institutions predicting the same events with a similar pool of participants.[1] History[edit] Prediction markets have a long and colorful lineage. Betting on elections was common in the U.S. until at least the 1940s, with formal markets existing on Wall Street in the months leading up to the race. Around 1990 at Project Xanadu, Robin Hanson used the first known corporate prediction market. In 2001, Intrade.com launched a prediction market trading platform from Ireland allowing real money trading between members on contracts related to a number of different categories including business issues, current events, financial topics, and more. In July 2003, the U.S. Accuracy[edit] Sources of inaccuracy[edit] Other issues[edit] Legality[edit]
Confidence Intervals In statistical inference, one wishes to estimate population parameters using observed sample data. A confidence interval gives an estimated range of values which is likely to include an unknown population parameter, the estimated range being calculated from a given set of sample data. (Definition taken from Valerie J. Easton and John H. McColl's Statistics Glossary v1.1) The common notation for the parameter in question is . , which is estimated through the The level C of a confidence interval gives the probability that the interval produced by the method employed includes the true value of the parameter Example Suppose a student measuring the boiling temperature of a certain liquid observes the readings (in degrees Celsius) 102.5, 101.7, 103.1, 100.9, 100.5, and 102.2 on 6 different samples of the liquid. In other words, the student wishes to estimate the true mean boiling temperature of the liquid using the results of his measurements. ). For a population with unknown mean + z* . . + t*
