Plot of dendrochronological age and estimation results of the Random forest model based on infrared spectra. Black line indicates perfect fit, very narrow 95% confidence bands are given in dashed lines (de facto not distinguishable from perfect fit line), 95% forecast bands in dotted lines (broader intervals); different countries are indicated by different colors, different symbols indicate different preservation conditions, n = 2,242.
