Figure 2.
Power comparisons based on 200 CEPH families in a homogeneous population with parental phenotypes. (a) The power comparisons for different values of R and r1 in the top R and exponential weighting methods (see Table 3 for the values of R and r1 corresponding to each scale on the x axis). (b) The power comparisons for different values of heritability h when R and r1 in the top R and exponential weighting methods are chosen by their optimal values.
