Abstract: The given digital sequence r₁,r₂,…,r_i,…,r_n in the interval (0, 1) on a computer, it is a important problem in the Monte Carlo computation to tost if that the digital sequence can be used as the uniformly distributed random numbers, The software system SUTEST in the statistical package SASD (a package for the Statistical Analysis of Stochastic Data) can be used to test statistical properties of the uniformly distributed random numbers in (0, 1) with 12 kinds,27 different testing methods and 61 statistics from homogeneity, randomnes,independence and simulative computing.SUTEST is developed with portable FORTRAN and can be used on a large, middle or small computer, and microcomputers too.
