REGRESSION: Residuals 1373<br />

• If PARTIALPLOT is included without any additional specifications, it produces a partial<br />

regression plot for every independent variable in the equation. The plots appear in the<br />

order the variables are specified or implied on the VARIABLES subcommand.<br />

• If variables are specified on PARTIALPLOT, only the requested plots are displayed. The<br />

plots appear in the order the variables are listed on the PARTIALPLOT subcommand.<br />

• At least two independent variables must be in the equation for partial regression plots to<br />

be produced.<br />

ALL Plot all independent variables in the equation. This is the default.<br />

varlist Plot the specified variables. Any variable entered into the equation can be<br />

specified.<br />

Example<br />

REGRESSION VARS=PLOT15 TO SAVINGS<br />

/DEP=SAVINGS<br />

/METH=ENTER<br />

/RESID=DEFAULTS<br />

/PARTIAL.<br />

• A partial regression plot is produced for every independent variable in the equation.<br />

OUTFILE Subcommand<br />

OUTFILE saves in an SPSS-format data file the parameter covariance or correlation matrix with<br />

parameter estimates, standard errors, significance values, and residual degrees of freedom for<br />

each term in the final equation. It also saves model information in XML format.<br />

• The OUTFILE subcommand must follow the last METHOD subcommand.<br />

• Only one OUTFILE subcommand is allowed. If you specify more than one, only the last<br />

one is executed.<br />

• You must specify at least one keyword and a valid filename in parentheses. There is no<br />

default.<br />

• You cannot save the parameter statistics as the working data file.<br />

• COVB and CORB are mutually exclusive.<br />

• MODEL cannot be used if split file processing is on (SPLIT FILE command) or if more than<br />

one dependent (DEPENDENT subcommand)variable is specified.<br />

COVB (filename) Write the parameter covariance matrix with other statistics. Specify<br />

the filename in full. REGRESSION does not supply an extension.<br />

CORB (filename) Write the parameter correlation matrix with other statistics. Specify<br />

the filename in full. REGRESSION does not supply an extension.<br />

MODEL (filename) Write model information to an XML file. Specify the filename in full.<br />

REGRESSION does not supply an extension. SmartScore and future releases<br />

of WhatIf? will be able to use this file.
