entcheck - estimates the entropy of a stream
entcheck [-N <bits>] [-s
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
- -N <bits>
- specifies the number of bits to use to predict the next bit.
- -s <streams>
- specifies the number of streams to use.
