WebMay 15, 2015 · The Chi-square statistic is defined as follows: The critical value for this test comes from a chi-square distribution with (9-1) = 8 degrees of freedom. For a significance level of 0.01, we get a critical value of 20.09. If the value of χ 2 is greater than this value, then we can reject a fit to Benford’s law with 99% certainty.
