Controls affecting belief comparisons and comparison diagrams

Belief sourcing for the comparison of hypotheses
 


tex2html_wrap_inline33790 tex2html_wrap_inline33790 Usage

tex2html_wrap_inline33806 tex2html_wrap_inline33806

The compare  control determines the belief stores from which covariances will be taken for the comparison of alternative variance hypotheses. Future belief comparisons then compare the alternative specifications tex2html_wrap_inline42760 to (over) tex2html_wrap_inline42762 for the base tex2html_wrap_inline40230 .  

Setting the diagram standard deviation scale
 


tex2html_wrap_inline33790 tex2html_wrap_inline33790 Usage

  • BD>control  cdscaler  = I tex2html_wrap_inline33712 where I is an integer.

  • The default value is I1=3 standard deviations.

tex2html_wrap_inline33806 tex2html_wrap_inline33806

The cdscaler  control specifies the number of standard deviations (relative to the model having the largest variance in that quadrant) represented by the node radius. It is used to determine how far along the radius, from centre to boundary, an observed value will be plotted. An observed value of 1.5 will be plotted half way to the boundary, by default. An obseved value of more than three will be plotted on the boundary, and shaded differently.  

Setting the radius of the observation mark
 


tex2html_wrap_inline33790 tex2html_wrap_inline33790 Usage

  • BD>control  cdradius =R tex2html_wrap_inline33712 where R is a real number such that tex2html_wrap_inline42382 .

  • by default R=0.

tex2html_wrap_inline33806 tex2html_wrap_inline33806

Observed values of eigenvectors comparing two alternative specifications are marked as small circles in quadrants on a belief comparison diagram. The label consists of a small circle, whose radius has a default value which can be reinstated by issuing the pcradius  control with argument tex2html_wrap_inline42384 . Otherwise a real value in (0,1) can be supplied. The default value is currently one third the radius of the default node size.
