As for t-digest vs. KLL or ReqSketch comparison, we have a paper with Graham and people from Splunk. I think t-digest was not updated much since then, so I think you can point to this paper for comparison. The upshot is that while t-digest is more accurate on well-behaved distributions, there are examples and distributions where it fails spectacularly (though these inputs are somewhat artificial). However, KLL and ReqSketch have much better update time than t-digest. |

This study is not relevant anymore. t-Digest code improved since then, and comparing with KLL was not the best idea. Now we have REQ sketch, which seems to be a better candidate for comparison.
