REGRESSION: Residuals 1371<br />

of $CASENUM and of the temporary variables for the 10 cases. The<br />

other temporary variables available for OUTLIERS are RESID, SRESID,<br />

SDRESID, DRESID, MAHAL, and COOK. The specification of any temporary<br />

variable other than these will result in an error.<br />

DURBIN Display Durbin-Watson test statistic in the Model Summary table.<br />

ID(varname) ID variable providing case labels for use with point selection mode in<br />

the Chart Editor. Applicable to scatterplots produced by SCATTERPLOT,<br />

PARTIALPLOT, and RESIDUALS. Any variable in the working data file can<br />

be named.<br />

SEPARATE Separate reporting of residuals statistics and plots for selected and<br />

unselected cases. This is the default.<br />

POOLED Pooled plots and statistics using all cases in the working file when<br />

the SELECT subcommand is in effect. (See the SELECT subcommand<br />

on p. 1363.) This is an alternative to SEPARATE.<br />

Example<br />

/RESID=DEFAULT ID(SVAR)<br />

• DEFAULT produces the default residuals statistics: Durbin-Watson statistic, a normal<br />

probability plot and histogram of ZRESID, and an outlier listing for ZRESID.<br />

• Descriptive statistics for ZRESID, RESID, PRED, and ZPRED are automatically displayed.<br />

• SVAR is specified as the case identifier on the outlier output.<br />

CASEWISE Subcommand<br />

CASEWISE requests a Casewise Diagnostics table of residuals. You can specify a temporary<br />

residual variable for casewise listing (via the PLOT keyword). You can also specify variables<br />

to be listed in the table for each case.<br />

• If CASEWISE is used without any additional specifications, it displays a Casewise Diagnostics<br />

table of ZRESID for cases whose absolute value of ZRESID is at least 3. By default,<br />

the values of the case sequence number, DEPENDENT, PRED, and RESID are listed for<br />

each case.<br />

• Defaults remain in effect unless specifically altered.<br />

DEFAULTS OUTLIERS(3), PLOT(ZRESID), DEPENDENT, PRED, and RESID. These<br />

are the defaults if the subcommand is used without specifications.<br />

OUTLIERS(value) List only cases for which the absolute standardized value of the listed variable<br />

is at least as large as the specified value. The default value is 3. Keyword<br />

OUTLIERS is ignored if keyword ALL is also present.<br />

ALL Include all cases in the Casewise Diagnostic table. ALL is the alternative to<br />

keyword OUTLIERS.<br />

PLOT(tempvar) List the values of the temporary variable in the Casewise Diagnostics table.<br />

The default temporary variable is ZRESID. Other variables that can be listed
