I know about the dendrochronology just enough that I can claim that I understand the basics. Let me someone correct if I am wrong: it is one of the "fingerprint" methods, based on pattern recognition and supported by the extensive database in a few words. Statistics, as a science by itself, works as a filter between the raw and final results. In my daily work, I use the similar method for determination of properties of unknown samples of biomass, comparing the pictures taken during the fast heating of biomass samples and comparing them with the referent database. Sometimes, I analyze the known sample, take the picture and add them to the database, aometimes I just use the database as a resource (in a few words, also). The other one example is something I've seen at the Carrara (at the university), where the same method was used (around year 2000) for determination of kind and origin of the marble's samples. Besides that, all uncertainties about the statistical methods can be very eficientlycleared with the first doctor carrying a Ph.D.
