Entropy = 7.995755 bits per byte.

Optimum compression would reduce the size
of this 398804956 byte file by 0 percent.

Chi square distribution for 398804956 samples is 2317786.02, and randomly
would exceed this value less than 0.01 percent of the times.

Arithmetic mean value of data bytes is 127.5044 (127.5 = random).
Monte Carlo value for Pi is 3.130867583 (error 0.34 percent).
Serial correlation coefficient is -0.006459 (totally uncorrelated = 0.0).
