Detailed Description

PseudoRandom Number Generator with Normal Distribution. Std. Normal Distribution generated from Uniform Distribution using method in "Simulation Modeling & Analysis 2nd Ed." by Law & Kelton pp. 491

Form name: NormalRand Slots: (I: inherited) (I) Seed: the seed to start the random number generator (I) Antithetic: boolean (true is x>0) for antithetic operation (return 1-U instead of U) (I) IncreasedPrecision: boolean (true is x>0) for using increased precision (53bit double) Mean: The Mean. StdDev: The Standard Deviation.

Output: (x=?) as a double via getNextRand(); method

Member Data Documentation

LcNumber* Eaagles::Basic::NormalRand::mean [private]

the Mean.

LcNumber* Eaagles::Basic::NormalRand::stdDev [private]

the Standard Deviation.

double Eaagles::Basic::NormalRand::secondRand [private]

Normal randoms are made in pairs, this will store the second and the calculation will only have to be done once every 2 calls.

bool Eaagles::Basic::NormalRand::secondFlag [private]

Flag to use the secondRand. Return secondRand iff true.
