CASEWISE Subcommand (REGRESSION command)

CASEWISE requests a Casewise Diagnostics table of residuals. You can specify a temporary residual variable for casewise listing (via the PLOT keyword). You can also specify variables to be listed in the table for each case.

  • If CASEWISE is used without any additional specifications, it displays a Casewise Diagnostics table of ZRESID for cases whose absolute value of ZRESID is at least 3. By default, the values of the case sequence number, DEPENDENT, PRED, and RESID are listed for each case.
  • Defaults remain in effect unless specifically altered.

DEFAULTS. OUTLIERS(3), PLOT(ZRESID), DEPENDENT, PRED, and RESID. These are the defaults if the subcommand is used without specifications.

OUTLIERS(value). List only cases for which the absolute standardized value of the listed variable is at least as large as the specified value. The default value is 3. Keyword OUTLIERS is ignored if keyword ALL is also present.

ALL. Include all cases in the Casewise Diagnostic table. ALL is the alternative to keyword OUTLIERS.

PLOT(tempvar). List the values of the temporary variable in the Casewise Diagnostics table. The default temporary variable is ZRESID. Other variables that can be listed are RESID, DRESID, SRESID, and SDRESID. The specification of any temporary variable other than these will result in an error. When requested, RESID is standardized and DRESID is Studentized in the output.

tempvars. Display the values of these variables next to the casewise list entry for each case. The default variables are DEPENDENT (the dependent variable), PRED, and RESID. Any of the other temporary variables can be specified. If an ID variable is specified on RESIDUALS, the ID variable is also listed.

Example

 /CASEWISE=DEFAULT ALL SRE MAH COOK SDR
  • This example requests a Casewise Diagnostics table of the standardized residuals for all cases.
  • ZRESID, the dependent variable, and the temporary variables PRED, RESID, SRESID, MAHAL, COOK, and SDRESID are for all cases.
