Figure 2.Accuracy of canid age clock. DNA methylation age (y-axis) versus chronological age (x-axis) for all canid samples (green = dog, blue = wolf). (A) Results obtained using a leave-one-out cross validation over all 108 samples. (B) Results obtained in each species separately using a leave-one-out cross validation. (C) Results obtained by regressing on all samples in one species and predicting age on samples from the other species. (D) Final models for each grouping of samples.
