Table 6.20 Hierarchy on histograms

   Variables:
      Y = Duration Time, histogram {[Ya1, Yb1), Yp1; [Ya2, Yb2], Yp2}
	  Hierarchy variables:
	    X1 with values: a, b or c
	    X2 with values: If X1=a, then X2=a1 or a2; else X2=NA
        X3 with values: If X2=a1, then X3=a11 or a12; else X3=NA
        X4 = Glucose, with values: If X1=a and X2=a2, then 
           X4, histogram {[X4a1, X4b1),X4p1; [X4a2, X4b2], X4p2}; else X4=NA
        X5 = Pulse Rate, with values: If X1=b, then 
           X5, histogram {[X5a1, X5b1), X5p1; [X5a2, X5b2], X5p2}]; else X5=NA       
         a b c, a1 a2, a11 a12 values entered as indicators (0, 1), intervals [z,z]
         NA entered as '.'
      X6 = Cholesterol, interval [X6a, X6b] (non-hierarchy variable)
