3046	 Computer Generation of Gamma Random Variables - II	 A rejection method is proposed for generating gamma variates with nonintegral shape parameter a a . This method is similar to other methods given by Fishman Wallace and Tadikamalla and is faster than these methods for a . The core storage requirements and the programming effort for the proposed method are similar to those of Wallace s or Tadikamalla s methods. The computational times for the proposed method remain fairly constant for medium and large values of a and are superior to times obtained by Ahrens and Dieter s method for all values of a. The proposed method is simpler than Ahrens and Dieter s method. Gamma variables rejection method computer methods
