This syntax will crosstabulate the groupid variables and performs the frequency test for each unique combination of crosstabulated values. Most of these tests involve testing whether the distribution of outputs produced by the supposedly random system is close enough to the distribution expected from a truly random sequence. For more details about how the nist statistical tests work, refer to section how to get started in the nist document a statistical test suite for random and pseudorandom. A unit test should call a method and test the returned value or object state against an expected value. For example, if x1 has 3 levels and x2 has 2 levels, there will be 6 frequency tests performed. Randomness tests or tests for randomness, in data evaluation, are used to analyze the distribution of a set of data to see if it can be described as random patternless. The purpose of this test is to determine whether that number of ones and zeros in a sequence are approximately the same as would be expected for a truly random sequence.
