PROC SIMILARITY: Sequence Scaling :: SAS/ETS(R) 9.22 User's Guide

The SIMILARITY Procedure

Sequence Scaling

The working input sequence can be scaled to the working target sequence. Sequence scaling is applied after normalization. Let $\text{[math]}$ be the working target sequence with mean $\text{[math]}$ and standard deviation $\text{[math]}$ . Let $\text{[math]}$ be the working input sequence and let $\text{[math]}$ be the scaled sequence. The scaling is defined as follows:

Standard is the standard normalization

$\text{[math]}$
Absolute is the absolute scaling

$\text{[math]}$
User-defined is a user-defined scaling created by the FCMP procedure.

Note: This procedure is experimental.
