Prediction of the PMI from gene expression in post-mortem samples. a Distribution of the PMI prediction error per tissue. b Regression of the real PMI versus the predicted individual PMI on the test set of 129 individuals. Plots in panels (c) and (d) illustrate two examples (GTEX-145MN and GTEX-145ME) of the prediction of the PMI for an individual based on the prediction of PMI from each tissue from the individual. For a given tissue, each yellow dot represents a prediction from each one of 13 different models. The black dot is the mean prediction of these 13 models. The green line represents the real PMI value for the individual. The individual PMI prediction is calculated as the average of the final tissue PMI predictions, and is represented by the red line
