k-mer Test Statistic Distribution mean, sv p-value
5-mer 0.6484 1, 0.0048 ≤0.0001
10-mer 0.7333 1, 0.0058 ≤0.0001
15-mer 0.6196 0.99, 0.0058 ≤0.0001
20-mer 0.8266 1, 0.0049 ≤0.0001
  1. Column 2 is the test statistic that served to capture how well cells from the same stage of progression cluster. Column 3 describes null distribution characteristics derived from permutation testing. Column 4 is the probability of occurrence of the test statistic in the null.
