Entropy = 7.961751 bits per byte.

Optimum compression would reduce the size
of this 374387184 byte file by 0 percent.

Chi square distribution for 374387184 samples is 20168698.69, and randomly
would exceed this value less than 0.01 percent of the times.

Arithmetic mean value of data bytes is 127.5067 (127.5 = random).
Monte Carlo value for Pi is 3.079589263 (error 1.97 percent).
Serial correlation coefficient is -0.004758 (totally uncorrelated = 0.0).
