Transform data

• About data transformations
  A data transformation is a means of mapping text values to new values, converting date values, or organizing numeric or date values into groups.
• Custom terms and mapped text values
  The Oracle Empirica Signal application offers two options for grouping values, such as a list of drugs or a list of events, together for use in a data mining run without affecting source data.
• Define variable cutpoints
  Categorization based on cutpoints is a type of data transformation.
• Convert dates
  For a variable that is based on a date value in the source data, you can convert the date value to a year, a half year, or a quarter year.
• Exclude synthetic values
  If source data includes other synthetic values, such as standardized MedDRA queries, you must exclude those values for the appropriate data configuration variable.
