Pattern frequency indicators include Pattern Frequency and Pattern Low Frequency.
There are two types of pattern frequency indicators:
  • The Pattern Frequency indicator computes the number of most frequent records for each distinct pattern.
  • The Pattern Low Frequency indicator computes the number of less frequent records for each distinct pattern.

These two indicators give patterns by converting alpha characters to a and numerics to 9.
