I implemented merge without calling compress() on the input and one tdigest at a time. Here is what happens with rank error after merge. The plot is too crowded. I can try plotting some things separately later. The rank error seems to be a bit worse compared to single tdigest, but does not seem to get worse with increased number of tdigests (even improves a little). I tried 32, 64 and 128 (the number does not have to be a power of 2, just a habit). <img width="1312" alt="TDigest 100 rank error after merge uniform random input" src="https://github.com/apache/datasketches-cpp/assets/13126686/c3af0c91-f3da-4d66-ad2b-500777440429";> -- This is an automated message from the Apache Git Service.
