            Calculates observed significance levels by using recursive 
        relationships to obtain a randomization (permutation) 
        distribution without having to directly examining all possible 
        permutations of the data.  It performs one and two sample 
        randomization tests and rank tests in the presence of an 
        arbitrary number of ties in the data. It reads data directly 
        from Systat system files.  An accompanying utility converts 
        ASCII files of numerical data into Systat system files, so it 
        is not necessary to own Systat to use PITMAN.
