Richard Guy often refers to the law of small numbers which states that there are not enough small numbers to satisfy all the demands placed on them.

Fréquences des lettres

Entrez un texte et calculez les fréquences d'apparition des 26 lettres de l'alphabet.

Ce petit programme vous permet de classer les lettres de l'alphabet en fonction de leur fréquence dans un texte que vous aurez préalablement placé dans l'aire ci-dessus.
Les lettres accentuées (é,è,ê,ë par exemple) sont remplacées par les lettres sans accents correspondantes (e dans l'exemple). Les majuscules sont remplacées par des minuscules. Les caractères autres que ceux de l'alphabet a-z sont éliminés avant la recherche (en particulier les espaces). Les lignes commençant par le signe dièze # sont des commentaires et ne sont pas prises en considération.
(Les fréquences des lettres en français peuvent être trouvées sur le site Lexique2 réalisé par Boris New & Christophe Pallier).

What is Grocer? Grocer is the econometric toolbox I (Eric Dubois) have developed for Scilab scilab.org, a matrix-oriented software similar to Gauss and Matlab. Like Scilab, it is free and open source.___It contains: most standard econometric capabilities: ...
some rare -and useful- ones: - a pc-gets like device, ... - a contributions device, that provides contributions of exogenous variables to an endogenous one for any dynamic equation
a -rough- interface with Excel and unlike Gauss or Matlab, it deals with true timeseries objects.

Some GAUSS applications in finance



What to do when non-normal is the norm. by Thomas Pyzdek
... For instance, most business processes don't produce normal distributions. There are many reasons why this is so. One important reason is that the objective of most management and engineering activity is to control natural processes tightly, eliminating sources of variation whenever possible. This control often results in added value to the customer. Other distortions occur when we try to measure our results. Some examples of "de-normalizing" activities include human behavior patterns, physical laws and inspection...
