WebbThe maximum value of entropy is log k, where k is the number of categories you are using. Its numeric value will naturally depend on the base of logarithms you are using. Using base 2 logarithms as an example, as in the question: log 2 1 is 0 and log 2 2 is 1, so a result greater than 1 is definitely wrong if the number of categories is 1 or 2.

When more than one lag k is tested, a correction for multiple hypotheses testing should be applied, e.g. False Discovery Rate (FDR) or Bonferroni correction. WebbThe entropy rate of a data source is the average number of bits per symbol needed to encode it. Shannon's experiments with human predictors show an information rate between 0.6 and 1.3 bits per character in English; the PPM compression algorithm can achieve a compression ratio of 1.5 bits per character in English text.
