The anomalous part of the cosmic electron-positron flux can be isolated within a Bayesian likelihood analysis. From the cosmic ray data the values of relevant cosmic ray propagation parameters can be also be inferred. I show how a tension arises between various cosmic ray datasets indicating an e+/e- anomaly. Then I show how to calculate the anomalous part of the PAMELA and Fermi-LAT measurements. I focus on the uncertainty of this 'signal'. Finally, I briefly compare this signal to some theoretical results predicting such an anomaly.
