Ordinal RegressionStatistics dialog box
ModelFit. Controls the displayof statistics that measure the overall model performance.
PseudoR-square. The R2statistic from linear regression does not have an exact counterpart
amongo rdinalregression models. Thereare, instead, multiple measures that attempt to mimic
the properties of the R2statistic.
Classificationtable. 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 relatedto the model
parameters.
Estimate. Displays estimates of the coefficients.
Exponentiatedestimate. Displays the base of the natural logarithm raised to the power of the
estimates of the coefficients. While the estimate has nice properties for statistical testing, the
exponentiated estimate, or exp(B), is easier to interpret.
Standarderror. Displaysthe standard error for each coefficient estimate.
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 ttest of each coefficient estimate. Thenull hypothesis for each test is that
thevalueofthecoefficientis 0.
Covariances of parameter estimates. Displays an est imate of the covariance matrix for the
model coefficients.
Correlationsof parameter estimates. Displays an estimate of the correlation matrix for the
model coefficients.
