Raw Blame History 

  1. PROGRAM FILE 142: SERIAL CORRELATION TEST OF RND FUNCTION.                      

  2.     ANSI STANDARD 8.4                                                           

  3.                                                                                 

  4. SECTION 142.1: SERIAL CORRELATION TEST OF RND FUNCTION.                         

  5.                                                                                 

  6. THIS PROGRAM COMPUTES THE SERIAL CORRELATION COEFFICIENT                        

  7. BETWEEN PAIRS OF ADJACENT RANDOM NUMBERS. THE RESULT IS                         

  8. COMPARED WITH THE EXPECTED VALUE FOR UNIFORM INDEPENDENT                        

  9. RANDOM NUMBERS. (BECAUSE THE PAIR I AND I+1 IS NOT                              

  10. COMPLETELY INDEPENDENT OF I+1, I+2, THE EXPECTED VALUE                          

  11. OF THE COEFFICIENT IS NOT EXACTLY ZERO.)                                        

  12.                                                                                 

  13. ***** THIS TEST IS INFORMATIVE ONLY *****                                       

  14.

  16.                                                                                 

  17. WITH ABOUT 95% PROBABILITY, WE EXPECT CORRELATION TO                            

  18. EQUAL -.001001  + OR -  6.31822E-2                                              

  19.                                                                                 

  20. THAT IS, WE EXPECT -6.41832E-2  <= CORRELATION <=  6.21812E-2                   

  21.                                                                                 

  22. ACTUAL CORRELATION = -4.90899E-2                                                

  23.                                                                                 

  24. *** INFORMATIVE TEST PASSED ***
