|Introduction to Scoring, Standardization, and Ranking Procedures
Several SAS/STAT procedures are utilities that produce an output
data set with new variables that are transformations of data in
the input data set. SAS/STAT software includes four of these
procedures. The RANK procedure
produces rank scores across observations, the SCORE procedure
constructs functions across the variables, and the STANDARD
and STDIZE procedures transform each variable individually.
- ranks the observations of each numeric variable
from low to high and outputs ranks or rank scores.
For a complete discussion of the RANK procedure,
refer to the SAS Procedures Guide.
- constructs new variables that are linear combinations
of old variables according to a scoring data set.
This procedure is used with the FACTOR procedure and other
procedures that output scoring coefficients.
- standardizes variables to a given mean and standard deviation.
For a complete discussion of PROC STANDARD, refer to
the SAS Procedures Guide.
- standardizes variables by subtracting a location measure and dividing
by a scale measure. A variety of location and scale measures are
provided. Such measures include the mean, median,
Huber's estimate, Tukey's biweight estimate, and Andrew's wave estimate.
