Not really. LZW is basically PPM with a static (and flat!) frequency prediction model. The contexts are build in a very similar way.
what you mean by "flat" and "static" applied to PPM? static PPM models exist - they carry probabilities as separate table very like static Huffman encoding. is "flat" the same as order-0?
I think he meant "flat" as in "pr(z) = 0 | 1"... As for "static", I'm not so sure that's actually correct.
