Using the constructed quantities

As you might guess, once our constructs are defined we can use them just as though we had defined them from the keyboard. As an example, we will use them to emphasise some technical properties of the canonical directions and of the belief structure generated by the canonical directions. Our name for the particular belief structure tex2html_wrap_inline9884 is the belief grid. Let us see what happens when we adjust the belief grid tex2html_wrap_inline9000 by tex2html_wrap_inline8806 , instead of adjusting the belief structure tex2html_wrap_inline8554 by tex2html_wrap_inline8806 .

The following commands define a new collection, or base, tex2html_wrap_inline8818 to contain our belief grid, adjust the collection tex2html_wrap_inline8818 by the collection tex2html_wrap_inline8608 , and then display various results of the adjustment:

BD>base: Y = Y$ tex2html_wrap_inline6116

BD>keep: -cd tex2html_wrap_inline6116

BD>adjust: [ Y / D ] tex2html_wrap_inline6116

BD>show: v+, e*, a+ tex2html_wrap_inline6116

giving the output shown in figure 22 (with further discussion in section 4.5). What should we notice about this sequence of commands and the output?
