1370 REGRESSION: Residuals<br />

• REGRESSION requests a single equation in which SAVINGS is the dependent variable and<br />

INCOME, POP15, and POP75 are independent variables.<br />

• RESIDUALS requests the default residuals output.<br />

• Because residuals processing has been requested, statistics for predicted values, residuals,<br />

and standardized versions of predicted values and residuals are displayed in a Residuals<br />

Statistics table.<br />

• CASEWISE requests a Casewise Diagnostics table for cases whose absolute value of<br />

ZRESID is greater than 3. Values of the dependent variable, predicted value, and residual<br />

are listed for each case.<br />

• SCATTERPLOT requests a plot of the standardized predicted value and the standardized<br />

residual.<br />

• PARTIALPLOT requests partial regression plots for all independent variables.<br />

• SAVE adds the standardized residual and the standardized predicted value to the working<br />

data file as new variables named STDRES and STDPRED.<br />

RESIDUALS Subcommand<br />

RESIDUALS controls the display and labeling of summary information on outliers as well as<br />

the display of the Durbin-Watson statistic and histograms and normal probability plots for the<br />

temporary variables.<br />

• If RESIDUALS is specified without keywords, it displays a histogram of residuals, a normal<br />

probability plot of residuals, the values of $CASENUM and ZRESID for the 10 cases with<br />

the largest absolute value of ZRESID, and the Durbin-Watson test statistic. The histogram<br />

and the normal plot are standardized.<br />

• If any keywords are specified on RESIDUALS, only the requested information and plots<br />

are displayed.<br />

DEFAULTS DURBIN, NORMPROB(ZRESID), HISTOGRAM(ZRESID), OUTLI-<br />

ERS(ZRESID). These are the defaults if RESIDUALS is used without<br />

specifications.<br />

HISTOGRAM(tempvars) Histogram of the temporary variable or variables. The default is<br />

ZRESID. You can request histograms for PRED, RESID, ZPRED,<br />

DRESID, ADJPRED, SRESID, SDRESID, SEPRED, MAHAL, COOK, and<br />

LEVER. The specification of any other temporary variable will result<br />

in an error.<br />

NORMPROB(tempvars) Normal probability (P-P) plot. The default is ZRESID. The other temporary<br />

variables for which normal probability plots are available are<br />

PRED, RESID, ZPRED, DRESID, SRESID, and SDRESID. The specification<br />

of any other temporary variable will result in an error. Normal<br />

probability plots are always displayed in standardized form; therefore,<br />

when PRED, RESID, or DRESID is requested, the standardized equivalent<br />

ZPRED, ZRESID or SDRESID is displayed.<br />

OUTLIERS(tempvars) The 10 cases with the largest absolute values of the specified temporary<br />

variables. The default is ZRESID. The output includes the values
