Further results for the partial adjustment

To display further details about the partial adjustment we can issue the usual SHOW:  command with various arguments, including for the first time the pc  option, which we use to display the path correlation:

BD>show: cd+,v+,a+,b,pc

 
Figure 28:  Adjusting additionally by

giving figure 28. The results displayed here are generally interpreted in the same way as before (in particular see sections 6.2.3, 6.2.4, and 6.2.5) but there are some extra details offered:

• the output displaying evaluations of the adjusted expectations contain two additional columns which show the actual change in expectation between the current and the previous adjustment; and this same change standardised relative to the partial variance resolved. Using the quantity to illustrate, these extra columns represent

  

• the bearing for the previous and current adjustments are given together with the bearing for the partial adjustment. Reading from left to right we have the coefficients for the linear combination representing the current bearing, , the bearing for the partial adjustment, , and the bearing for the initial adjustment by , . You should be able to verify by inspection the property

  

  Underneath this output can be found the size and expected size of each adjustment, together with the size ratio for each adjustment.

• the path correlation, , being the prior correlation between the initial and partial bearings.
