Benford's Law - Moments

Moments

Moments of random variables for the digits 1 to 9 following this law have been calculated:

  • mean 3.440
  • variance 6.057
  • skewness 0.796
  • kurtosis 0.548

For the first and second digit distribution these values are also known:

  • mean 38.590
  • variance 621.832
  • skewness 0.772
  • kurtosis 0.547

A table of the expected values of the first two digits according to Benford's law is available, as is the population correlation between the first and second digits: ρ2 = 0.0561.

Famous quotes containing the word moments:

    The amelioration of the world cannot be achieved by sacrifices in moments of crisis; it depends on the efforts made and constantly repeated during the humdrum, uninspiring periods, which separate one crisis from another, and of which normal lives mainly consist.
    Aldous Huxley (1894–1963)

    There are thoughts which are prayers. There are moments when, whatever the posture of the body, the soul is on its knees.
    Victor Hugo (1802–1885)

    Science with its retorts would have put me to sleep; it was the opportunity to be ignorant that I improved. It suggested to me that there was something to be seen if one had eyes. It made a believer of me more than before. I believed that the woods were not tenantless, but choke-full of honest spirits as good as myself any day,—not an empty chamber, in which chemistry was left to work alone, but an inhabited house,—and for a few moments I enjoyed fellowship with them.
    Henry David Thoreau (1817–1862)
