variableSyncParms Data Table

The variableSyncParms data table is an optional data table, and its alias is varsyncs. It is used to specify the parameters for synchronizing the beliefs of interval variables across the branches of nominal variables. It has the following columns:

intervalvar

specifies the interval variable for which synchronization parameters are specified.

nominalvar

specifies the nominal variable that is used in the (nominalvar, varlevel) pair that defines the branch for synchronization parameters.

varlevel

specifies the level of nominal variable that is used in the (nominalvar, varlevel) pair that defines the branch for synchronization parameters.

mean

specifies the mean of the belief that is used while the interval variable is being synchronized on this branch of the (nominalvar, varlevel) pair.

sdev

specifies the standard deviation of the belief that is used while the interval variable is being synchronized on this branch of the (nominalvar, varlevel) pair.

If the belief that is specified by the (mean, sdev) pair is not supplied for an interval variable in this data table, then the interval variable gets the belief during synchronization from the maximum probability branch of the nominal variable. This data table also specifies the value of the syncSize variable for nominal variables. If only the nominalvar and mean columns are populated, then the value in the mean column is the syncSize variable value for the nominalvar column. The default syncSize variable value is 20. If all interval variables get their beliefs from the maximum probability branch and all nominal variables use the default syncSize variable value, then this data table is not needed.
