Statistical test of random number generators Uniformity test: Break up the interval between 0 and 1 into a large number of small bins and after generate a large number of random numbers check for uniformity in the numbers of entries in each bins(uniform histogram Parking lot test: Plot points in an m-dimensional space where the m-coordinates of each point are determined by m-successive calls to the random number generator. Then, look for regular structure (resulting from some correlation) Illustration good generator(parking lot test) bad generator(parking lot test) 0Statistical test of random number generators Uniformity test: Break up the interval between 0 and 1 into a large number of small bins and after generate a large number of random numbers check for uniformity in the numbers of entries in each bins (uniform histogram).
