Source of variances and covariances required

Refer to §20.6. There are four sources to consider, the first three are as for any general adjustment. The source for tex2html_wrap_inline36752 is set using the priorvar  control. The source for tex2html_wrap_inline39806 is set by using the betweenvar  control. The source for tex2html_wrap_inline39808 is set by using the infovar  control. In addition to these usual sources, we need also the source for the covariances between different observations, tex2html_wrap_inline39810 . This is set by using the modelvar  control, and should typically be a source different to the one set by the infovar  control. For example, suppose that tex2html_wrap_inline36752 , L, and G+U have been entered into belief store number 1, and that G has been entered into belief store number 2. The appropriate command line defining the belief sources is

BD>control  priorvar =1,betweenvar =1,infovar =1,modelvar =2 tex2html_wrap_inline33712
