Each error plot is converted into a sequence of symbols (e.g.
▼▽░█░△▲)
where each symbol indicates for given time step whether the experiment is significantly better or worse than the control on different confidence levels.
Different colours are used for symbols comparing control and experiment activity or spread: purple â–¼ indicates the experiment is more active or has larger spread than the control and green â–² the opposite.
Symbol legend: for a given forecast step... â–² experiment better than control statistically significant with 99.7% confidence â–³ experiment better than control statistically significant with 95% confidence â–‘ experiment better than control statistically significant with 50% confidence â–ˆ not really any difference between control and experiment â–‘ experiment worse than control statistically significant with 50% confidence â–¾ experiment worse than control statistically significant with 95% confidence â–¼ experiment worse than control statistically significant with 99.7% confidence )
red = the experiment (esuite) is worse than the control. blue = the experiment (esuite) is better than control.
purple = the experiment is more active than the control. green = the experiment is less active than control.
Colour hue and saturation are proportional to normalised difference value.
A colour-framed cell indicate the differences are statistically significant on 95% confidence level.
However, where the differences are not significant on at least 0% level they are masked by a light grey box.
For more details:
Hover the mouse cursor over a cell and a small information window pops up with the difference values.
Click on a cell and a graph of normalized differences will show.
