The scale functions are:

  • ScaleMap, which takes a data set and outputs its statistical information (assembled at the vworker level)
  • Scale, which takes ScaleMap output and outputs scaled (normalized) values for the input data set

    You can use Scale output as input to distance-based analysis functions, such as KMeans.

  • ScalePrinter, which takes ScaleMap output and outputs global statistical information for the entire input data set
  • PartitionScale, which scales the sequences in each partition independently, using the same formula as Scale
