Model Fit. Controls the display of statistics that measure the overall model performance.
Pseudo R-square. The R
2
statistic from linear regression does not have an exact counterpart
among ordinal regression models. There are, instead, multiple measures that attempt to mimic
the properties of the R
2
statistic.
Classification table. Displays the tabulated cross-classifications of the observed category by
the model-predicted category on the dependent variable.
Parameters. This group allows you to control the display of statistics related to
the model
parameters.
Estimate. Displays estimates of the coefficients.
Exponentiated estimate. Displays the base of the natural logarithm raised to the power of the
estimates of the coefficients. While the estimate has nice properties for stati
stical testing, the
exponentiated estimate, or exp(B), is easier to interpret.
Standard error. Displays the standard error for each coefficient e stimate.
Confidence interval. Displays a confidence interval for each coefficient estimate. The
confidence level for the interval is set in the Options dialog box.
Ttest. Displays a t test of each coefficient estimate. The null hypothesis for each test is that
thevalueofthecoefficient is 0.
Covariances of parameter estimates. Displays an estimate of the covariance
matrix for the
model coefficients.
Correlations of parameter estimates. Displays an estimate of the correlation matrix for the
model coefficients.
