LZ complexity algorithm

Could you please explain me the thing: how does LZ complexity algorithm incorporate with data compression? Does it (or meant to) compress data or it only estimates the number of unique substrings in vocabulary?

Thanks!

You can calculate LZ complexity without actually doing any compression, although the calculation will look a lot like what happens when LZ-compressing the input data. See, e.g., calculating Lempel-Ziv (LZ) complexity (aka sequence complexity) of a binary string where one of the answers has (non-compressing) code for calculating LZ complexity.
