Quantile calculation - Estimation type documentation


when you select the Quantile aggregation in the GroupBy node, you can select the 'Estimation type' in the advanced tab. The possible types are 'LEGACY', 'R_1', 'R_2', ... , 'R_9'.

Can someone point to the documentation of what these different types mean?

if you go to the section "Estimating quantiles from a sample" in the following WikiPedia Article: https://en.wikipedia.org/wiki/Quantile 

There the R1-R9 is explained.

Could you please give a similar reference from literature for the Legacy method? I do see the formula in Knime help.
