| <h1 id="kll-sketch-accuracy-and-size">KLL Sketch Accuracy and Size</h1> |
| |
| <p>The accuracy of the KLL quantile sketch is a function of the configured <i>K</i>, which also affects the overall size of the sketch (default K = 200).</p> |
| |
| <p>The accuracy of quantiles sketches is specified and measured with respect to the <em>rank</em> only, not the quantiles.</p> |
| |
| <p>The KLL Sketch has <em>absolute error</em>. For example, a specified rank accuracy of 1% at the median (rank = 0.50) means that the true quantile (if you could extract it from the set) should be between <em>getQuantile(0.49)</em> and <em>getQuantile(0.51)</em>. |
| This same 1% error applied at a rank of 0.95 means that the true quantile should be between <em>getQuantile(0.94)</em> and <em>getQuantile(0.96)</em>. In other words, the error is a fixed +/- epsilon for the entire range of ranks.</p> |
| |
| <p>The approximate rank error values listed in the second row of the header in the table below can be computed using the function <i>KLLSketch.getNormalizedRankError(int k, false)</i>. The third row shows the double-sided error that applies to a portion of the distribution such as an element of PMF (bar in a histogram) that is a subject to rank error on both sides. It can be computed using the function <i>KLLSketch.getNormalizedRankError(int k, true)</i>.</p> |
