Examples of umontreal.iro.lecuyer.randvar.GammaAcceptanceRejectionGen

umontreal.iro.lecuyer.randvar.GammaAcceptanceRejectionGen
This class implements gamma random variate generators using a method that combines acceptance-rejection with acceptance-complement. It uses acceptance-rejection for α < 1 and acceptance-complement for α >= 1. For each gamma variate, the first uniform required is taken from the main stream and all additional uniforms (after the first rejection) are obtained from the auxiliary stream.

         throw new NullPointerException ("stream is null");
      this.stream = stream;
      dimension = alphas.length;
      ggens = new GammaAcceptanceRejectionGen[alphas.length];
      for (int k = 0; k < alphas.length; k++)
         ggens[k] = new GammaAcceptanceRejectionGen
            (stream, new GammaDist (alphas[k], 1.0/2.0));
   }
