entcheck - estimates the entropy of a stream

entcheck  estimates the entropy of its standard input.  It uses the previous bits bits (16 by default) to
       predict the next bit, and estimates the entropy based on the level of surprise, that is to say the base-2
       logarithm of the probability of seeing the given string of bits.

       In some scenarios, such as the output of an 8-bit DAC, some bits are special: entropy then  needs  to  be
       predicted  per  bit  over  the width of the input data. The -s option sets the width of the input data in
       this case.

-N <bits>
              specifies the number of bits to use to predict the next bit.

       -s <streams>
              specifies the number of streams to use.
