چکیده انگلیسی

This commentary highlights a regularly occurring misinterpretation of the widely used expressed population signal (EPS). Based on thorough examination of the scientific article introducing EPS, I show that I) EPS was not meant to be a measure for the suitability of tree-ring data for climate reconstruction, and II) that the frequently used – but arbitrarily chosen – threshold of 0.85 was not meant to be used in combination with EPS. Instead, the less frequently used subsample signal strength (SSS) was intended for a respective application, i.e. as a measure of decreasing predictive power of transfer functions due to reductions in the sample size of underlying tree-ring series back in time. I conclude that classical transfer function quality statistics should be preferred over the erroneous application of EPS in the context of evaluating the suitability of dendrochronological data for climate reconstructions.
