Hi, I am new to DataSketches. I know Datasketches provides an *approximate* calculation of statistics with *mathematically proven error bounds*.
My question is: Say that I am constrained to take a sampling of the original data set before handling it to Datasketches (for example, I cannot take more than 10.000 random rows from a table). What would be the consequence of this previous sampling in the "mathematically proven error bounds" of the Datasketches statistics, relative to the original data set? Best, Sergio
