This article describes how to transform the data for each selected variable set and create a new variable set that contains the transformed data after scaling the values for each variable so that the data values all lie between 0 and 1. Consider the data below:
For each column/variable in the data, this QScript will subtract the minimum of the column from each entry and then divide by the range (maximum minus minimum) of the column to yield the following:
Requirements
- A Displayr document that contains one or more Nominal - Multi, Ordinal - Multi, Numeric - Multi, Numeric - Grid, Nominal, Ordinal, or Numeric variable sets.
Method
- Select one or more variable sets in the Data Sources tree.
- Hover and click Plus (+) > Numeric Transformations > Scale > Unit Interval Within Variable.
- For each selected variable set, a new variable set is created just below the original.
