The HPCLUS Procedure

INPUT Statement

INPUT variables <LEVEL=BINARY | NOMINAL | ORDINAL | INTERVAL>;

The INPUT statement specifies the names of the variables to be used in clustering. It names one or more input variables that use common options. HPCLUS supports only nominal variables or only interval variables in the INPUT statement. You can include the following option in each INPUT statement:

LEVEL=BINARY | NOMINAL | ORDINAL | INTERVAL

specifies the level of measurement of the variables. For clustering, only interval, binary, and nominal variables are accepted.

Note: If you specify LEVEL=ORDINAL, the variables are ignored by the HPCLUS procedure.

By default, LEVEL=INTERVAL for numeric variables, and LEVEL=NOMINAL for categorical character variables. Binary variables are considered to be nominal variables.
