The accuracy in prediction of lifestyle values varies, while the ranking remains consistent. For each of 1,000 iterations, lifestyle values were predicted and compared with their known true values, through simulation. Each simulation assumes 1,000 individuals and m time points. (A) Evaluates the difference between the proportion accounted for by the environment as determined by the true lifestyle effect with that of the predicted lifestyle effect. This result indicates that the accuracy of these predictions has a high variation, but that by increasing the number of time points it is possible to obtain more accurate predictions. (B) Shows the distributions of Spearman rank correlations between the true lifestyle and predicted lifestyle values. This result indicates that the ranking of individuals based on their predicted lifestyle is highly concordant with the true lifestyle ranking.
