Optimum compression would reduce the size of this 1287733760 byte file by 0 percent. Chi square distribution for 1287733760 samples is 262.74, and randomly would exceed this value 50.00 percent of the times. Arithmetic mean value of data bytes is 127.4979 (127.5 = random). Monte Carlo value for Pi is 3.141541200 (error 0.00 percent). Serial correlation coefficient is -0.000033 (totally uncorrelated = 0.0). root@trb-dev:/home/mod6/fg5#
