NONPARALLEL Subcommand (CSORDINAL command)

The NONPARALLEL subcommand requests various statistics associated with a general cumulative link model with non-parallel lines where a separate regression line is fitted for each response category except for the last.

TEST. Test of parallel lines assumption. Test whether regression parameters are equal for all cumulative responses. The general model with non-parallel lines is estimated and the Wald test of equal parameters is applied.

PARAMETER. Parameters of the general model with non-parallel lines. The general model is estimated using the same convergence criteria as for the original model. Both parameters and their standard errors are estimated.

COVB. Covariance matrix for the general model parameters.
