Name

adams.flow.transformer.SpreadSheetRandomSystematicSample

Synopsis

Performs random systematic sampling on the rows of the incoming spreadsheet.
Divides the rows into N blocks with N being the sample size. Then chooses a random starting position. Adds the row the output increments the position by the sample size. Position wraps around if output hasn't yet reached sample size.
