These configuration properties are different for each of the following plots and summarized below with each plot.
## Test Design
-* Stream Length (SL): 2^20
+* Stream Length (SL): 2^20 = 1,048,576 floats
* Stream Values: Natural numbers, ℕ<sub>1</sub>, from 1 to SL, expressed as 32-bit floats.
* Y-axis: The absolute error of the sketch *getRank(value)* method.
* X-axis: The normalized rank [0.0, 1.0]
-* Plot Points (PP): 100. Equally spaced points along the X-axis starting at *1.0/SL* and ending at 1.0.
+* Plot Points (PP): 100. Equally spaced points along the X-axis starting at 0 and ending at 1.0.
* Trial:
- * The stream is generated according to the chosen adversarial pattern.
- * At each Plot Point, we compute the rank errors of all ~10K points from the preceding PP to the current PP.
- * These 10K error values are fed into an error quantile sketch associated with the current PP.
- * 3 quantile values (-3sd, Median, +3sd) are extracted from each error sketch. These error quantiles correspond to the standard normal distribuion at the median, and +/- 3SD, where SD stands for Standard Deviation from the mean.
+ * The stream is generated according to the chosen adversarial pattern and presented to the sketch.
+ * Execute *estRanks[] = getRanks(trueValues[])* from the sketch where the array of *trueValues[]* are the 100 equally spaced values along the x-axis that exactly correspond to the above Plot Points. The *estRanks[]* is the array of the sketch's estimates of the ranks of the given *trueValues*.
+ * Computes the absolute error: *estRanks[i] - trueRanks[i]* for each Plot Point and submits this error to a corresponding array of standard qantile sketches, with one quantile sketch assigned to each Plot Point.
+* Trials:
+ * 2^12 trials are executed. This produces a distribution of error at each Plot Point held by the error quantile skeches.
+ * **Note:** With these tests, since we do not shuffle the stream with each trial, randomization is due to just the internal random process of the sketch itself.
+ * Extract 7 quantiles from the error quantile sketches at each Plot Point. These error quantiles correspond to the standard normal distribuion at the median, +/- 1SD, +/- 2SD and +/- 3SD, where SD stands for Standard Deviation from the mean.
* Plotting:
- * Each of the error quantiles are connected by lines to form contours of the error distribution where the area between the +/- 3SD contours is the 99.7% confidence interval.
+ * Each of the error quantiles are connected by lines to form contours of the error distribution where the area between the +/- 1SD contours is the size of the 68% confidence interval; between the +/- 2SD coutours is the 95.4% confidence interval; and between the +/- 3SD contours is the 99.7% confidence interval.
* In addition to the error contours. 6 dashed contours (with colors corresponding to the error contours) represent the a priori estimates of the error at each of the +/- standard deviations computed from the sketch's *getRankLowerBound(double, int)* and *getRankUpperBound(double, int)* methods.
