         Figure  12.2.  Average  error  difference Ae  (over  all  points  p k  e D)  between
               BME  and SK as a function of the time interval  At.





























         Figure  12.3.  Map  of  the  SK  estimation  error  standard deviation  e SK(p k);
               At  =  0.5.


         In  Figure  8.2  (p.  152),  the  average  standard  deviation  of  the  estimate  over

         all  200  realizations,  expressed by  cr BME(pk)  — ( BME(Pk)}<  was  plotted  for
         all p h  €  D.  In  Figure  8.3,  the  average estimation  error  standard  deviation
                 was calculated over the 200 realizations, and the (actual) eBME(pk)
         values  were found  to  be of  the  same  magnitude  as the  <r BME(Pk}  values.  In
         Figure 12.3,  the average estimation error standard  deviation for SK over the 200
