CONDITION Subcommand (PREFSCAL command)

CONDITION specifies the range of proximities that are compared within one transformation list. The TRANSFORMATION subcommand specifies the type of transformation.

ROW. Row conditional. Only the proximities within each row are compared with each other. The comparison is carried out for each row separately. This setting is the default.

MATRIX. Matrix conditional. Only the proximities within each source are compared with each other. The comparison is carried out for each source separately.

UNCONDITIONAL. Unconditional. This specification is appropriate when the proximities in all sources can be compared with each other, and it results in a single transformation of all sources simultaneously.

• Note that if there is only one source, MATRIX and UNCONDITIONAL yield the same result.

Example

PREFSCAL var01 TO var09
  /CONDITION = UNCONDITIONAL
  /TRANSFORMATION = LINEAR(INTERCEPT).

• In this example, the proximities are linearly transformed, including an intercept. The transformation is carried out over all proximities simultaneously.
