SIMILARITY Procedure

Sequence Normalization

The working (input or target) sequence can be normalized prior to further analysis. Let q Subscript i be the original sequence with mean mu Subscript q and standard deviation sigma Subscript q, and let r Subscript t be the normalized sequence. The normalizations are defined as follows:

  • Standard is the standard normalization

    r Subscript i Baseline equals left-parenthesis q Subscript i Baseline minus mu Subscript q Baseline right-parenthesis slash sigma Subscript q

  • Absolute is the absolute normalization

    r Subscript i Baseline equals left-parenthesis q Subscript i Baseline minus min left-parenthesis q Subscript i Baseline right-parenthesis right-parenthesis slash left-parenthesis max left-parenthesis q Subscript i Baseline right-parenthesis minus min left-parenthesis q Subscript i Baseline right-parenthesis right-parenthesis

  • User-defined is a user-defined normalization created by the FCMP procedure.
