Functions ¶
func Estimate ¶
Estimate returns a normalized compressibility estimate of block b. Values close to zero are likely uncompressible. Values above 0.1 are likely to be compressible. Values above 0.5 are very compressible. Very small lengths will return 0.
func ShannonEntropyBits ¶
ShannonEntropyBits returns the number of bits minimum required to represent an entropy encoding of the input bytes. https://en.wiktionary.org/wiki/Shannon_entropy
