Calculation of the Lempel Ziv complexity c(n) needs to define an alphabet A, that is, the set of symbols which compose the sequence S (for a binary string, A is simply {0,1}).
Entropy parameters, Lempel Ziv complexity indices, variability parameters in time domain, and PRSA derived indices exhibit excellent performance in classification of normal and IUGR population.
Unisys holds a patent on a compression/decompression algorithm called LZW, named after Lempel Ziv and Welch, who were three engineers working for Sperry in the 1980s.
