826 LOGLINEAR<br />

The following keywords can be used on PRINT:<br />

FREQ Observed and expected cell frequencies and percentages. This is displayed<br />

by default.<br />

RESID Raw, standardized, and adjusted residuals. This is displayed by default.<br />

DESIGN The design matrix of the model, showing the basis matrix corresponding to<br />

the contrasts used.<br />

ESTIM The parameter estimates of the model. If you do not specify a design on the<br />

DESIGN subcommand, LOGLINEAR generates a saturated model and displays<br />

the parameter estimates for the saturated model. LOGLINEAR does<br />

not display parameter estimates or correlation matrices of parameter estimates<br />

if any sampling zero cells exist in the expected table after delta is<br />

added. Parameter estimates and a correlation matrix are displayed when<br />

structural zeros are present.<br />

COR The correlation matrix of the parameter estimates. Alias COV.<br />

ALL All available output.<br />

DEFAULT FREQ and RESID. ESTIM is also displayed by default if the DESIGN subcommand<br />

is not used.<br />

NONE The design information and goodness-of-fit statistics only. This option overrides<br />

all other specifications on the PRINT subcommand. The NONE option<br />

applies only to the PRINT subcommand.<br />

Example<br />

LOGLINEAR A(1,2) B(1,2)<br />

/PRINT=ESTIM<br />

/DESIGN=A,B,A BY B<br />

/PRINT=ALL<br />

/DESIGN=A,B.<br />

• The first design is the saturated model. The parameter estimates are displayed with ESTIM<br />

specified on PRINT.<br />

• The second design is the main-effects model, which tests the hypothesis of no interaction.<br />

The second PRINT subcommand displays all available display output for this model.<br />

PLOT Subcommand<br />

PLOT produces optional plots. No plots are displayed if PLOT is not specified or is specified<br />

without any keyword. Multiple PLOT subcommands can be used. The specifications are<br />

cumulative.<br />

RESID Plots of adjusted residuals against observed and expected counts.<br />

NORMPROB Normal and detrended normal plots of the adjusted residuals.<br />

NONE No plots.<br />

DEFAULT RESID and NORMPROB. Alias ALL.
