### Data Members

## Class Description

TRandom* randomGenerator()

     Return a pointer to a singleton random-number generator
     implementation. Creates the object the first time it is called.

RooQuasiRandomGenerator* quasiGenerator()

     Return a pointer to a singleton quasi-random generator
     implementation. Creates the object the first time it is called.

Double_t uniform(TRandom *generator)

     Return a number uniformly distributed from (0,1)

void uniform(UInt_t dimension, Double_t vector[], TRandom *generator)

     Fill the vector provided with random numbers uniformly distributed from (0,1)

UInt_t integer(UInt_t n, TRandom *generator)

     Return an integer uniformly distributed from [0,n-1]

Double_t gaussian(TRandom *generator)

     Return a Gaussian random variable with mean 0 and variance 1.

Bool_t quasi(UInt_t dimension, Double_t vector[], RooQuasiRandomGenerator *generator)

     Return a quasi-random number in the range (0,1) using the
     Niederreiter base 2 generator described in Bratley, Fox, Niederreiter,
     ACM Trans. Model. Comp. Sim. 2, 195 (1992).
