Detailed Description

Description of a variable (field).

Both currently sequences implemented are :

• "sobol"
• "halton"

Example of use

Firstly, a pointer to a TDataServer is constructed

TDataServer *tdsqmc = new TDataServer("tdsQMC", "Test for qMC");
tdsqmc->addAttribute( new TAttribute("x_{1}", -1.0 , 2.) );
tdsqmc->addAttribute( new TAttribute("x_{2}",  0.0 , 3.) );
tdsqmc->addAttribute( new TAttribute("x_{3}",  1.0, 1.5) );

Then, a pointer to an object TQMC of the chosen sequence ("sobol"|"halton") is constructed from this TDataServer , and the generateSample() method is applied

TQMC * qmc = new TQMC(tdsqmc, "sobol", 300);
qmc->generateSample();

Bibliography source

The bibliography is :

• Eric Thiemard's thesis intitulated Sur le Calcul et la Majoration de la disrepance a l'Origine - Lausanne, EPFL, 2000 (in french)
• Lectures Notes in statistics intitulated Random and Quasi-Random Points Sets

  He proposes a theorical presentation of the Digital Point Sets of Gerhard Larcher.Anyway, this book is mostly oriented to the tests for checking that the generated points are really random ones.
