Power plot.
a. Log-additive model for association and co-dominant model for survival, recruiting probability = 1. In this case, Mixed and the Child+Spouse designs are identical, and the minor difference in the figure was due to computation precision;
b. Log-additive model for association and co-dominant model for survival, recruiting probability = 0.7;
c. Log-additive model for association and co-dominant model for survival, recruiting probability = 0.5;
d. Dominant model for both association and survival, recruiting probability = 1; In this case, Mixed and the Child+Spouse designs are identical, and the minor difference in the figure was due to computation precision;
e. Dominant model for both association and survival, recruiting probability = 0.7;
f. Dominant model for both association and survival, recruiting probability = 0.5.
