Deleted commands

Sabre manual

The following commands in Sabre 3.1 have been deleted in Sabre 4.0:

DROP
This command was previously used in conjunction with LAG in order to perform a likelihood ratio test on the significance of the lag parameter. The significance of the lag parameter must now be inferred from its estimate and standard error.

HELP
The HELP command is considered to be redundant now that the online user manual is available.

INFO
The INFO command is considered to be redundant since the information is available on the web site.

LAG
The LAG command has been withdrawn because lagged response models can be fitted via simple use of a user-defined dummy variable.

MARKOV
Markov models can now be solved using the new and more general DEPEND command.

MONITOR
This command was previously used to determine whether or not progress of the fitting algorithm was displayed. Monitoring is now permanently switched on.

ORDINAL
This command has been replaced by ORDERED. The previous method was a continuation ratio-type generalisation which expanded the ordinal response dataset into a sequence of binary responses and then fitted binary models to the resulting dataset. The new method fits genuine ordered response models, both standard and random effects (ORDINAL did not do random effects).

POISSON
This command was previously used to specify a Poisson model. This is now done via the 'FAMILY P' command.

RETURN
This command previously provided compatibility with the GLIM software package. This is no longer relevant.

UNITS
This command previously provided compatibility with the GLIM software package. This is no longer relevant.

FIT +
FIT -
LFIT +
LFIT -
The + and - options of the FIT and LFIT commands have been removed. The list of variates must now be specified in full.
