All but one of the following controls determine the belief store from
which covariances will be taken for all types of adjustment (that is,
for the ADJUST: , COHERENCE: and
SCAN: commands). The exceptions are the ac and
scac controls, used
for storing adjusted covariances. Assume the scenario that the base
is to be adjusted by 
.
Usage
BD>control modelvar =I
The modelvar control sets the source for ``different situation''
variances and covariances specified for the elements of
BD>control priorvar =I
The priorvar control sets the source for
BD>control betweenvar =I
The betweenvar control sets the source for
BD>control infovar =I
The infovar control sets the source for ``same situation''
variances and covariances specified for the elements of
The setting of this control is referenced
for all exchangeable adjustments, and also for coherence checks carried
out using the COHERENCE: command.
