Jules Regnault
Jules Augustin Frédéric Regnault (; 1 February 1834, Béthencourt – 9 December 1894, Paris) was a French stock broker's assistant who first suggested a modern theory of stock price changes i''Calcul des Chances et Philosophie de la Bourse''(1863), using a random walk model. A key conclusion appears on Page 50: "''l'écart des cours est en raison directe de la racine carrée des temps''", in English: "the deviation of prices is directly proportional to the square root of time". He is also one of the first authors who tried to create a "stock exchange science" based on statistical and probabilistic analysis. His hypotheses were used by Louis Bachelier. Biography During the first years of his life, Jules Regnault lived in the département du Nord (France) where his father worked. When his father died on 16 January 1846 in Paris, his family moved to Brussels, where Odilon, Jules’ brother, became a writer and a student at the Université libre de Bruxelles in advanced mat ...

Econometrics
Econometrics is an application of statistical methods to economic data in order to give empirical content to economic relationships. M. Hashem Pesaran (1987). "Econometrics", '' The New Palgrave: A Dictionary of Economics'', v. 2, p. 8 p. 8–22 Reprinted in J. Eatwell ''et al.'', eds. (1990). ''Econometrics: The New Palgrave''p. 1 p. 1–34Abstract ( 2008 revision by J. Geweke, J. Horowitz, and H. P. Pesaran). More precisely, it is "the quantitative analysis of actual economic phenomena based on the concurrent development of theory and observation, related by appropriate methods of inference." An introductory economics textbook describes econometrics as allowing economists "to sift through mountains of data to extract simple relationships." Jan Tinbergen is one of the two founding fathers of econometrics. The other, Ragnar Frisch, also coined the term in the sense in which it is used today. A basic tool for econometrics is the multiple linear regression model. ''Econome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Larousse
Pierre Athanase Larousse (; 23 October 18173 January 1875) was a French grammarian, lexicographer and encyclopaedist. He published many of the outstanding educational and reference works of 19th-century France, including the 15-volume . Early life Pierre Larousse was born in Toucy, where his father was a blacksmith. At the age of sixteen he won a scholarship at the teaching school in Versailles. Four years later, he returned to Toucy to teach in a primary school, but became frustrated by the archaic and rigid teaching methods. In 1840 he moved to Paris to improve his own education by taking free courses. Career From 1848 to 1851, Larousse taught at a private boarding school, where he met his future wife, Suzanne Caubel (although they did not marry until 1872). Together, in 1849, they published a French language course for children. In 1851 he met Augustin Boyer, another disillusioned ex-teacher, and together they founded the ''Librairie Larousse et Boyer'' (Larousse and Boye ...
