20.500.12556/DiRROS-8217 DendroTools : R package for studying linear and nonlinear responses between tree-rings and daily environmental data We introduce in this paper the dendroTools R package for studying the statistical relationships between tree-ring parameters and daily environmental data. The core function of the package is daily_response(), which works by sliding a moving window through daily environmental data and calculating statistical metrics with one or more tree ring proxies. Possible metrics are correlation coefficient, coefficient of determination and adjusted coeffi- cient of determination. In addition to linear regression, it is possible to use a nonlinear artificial neural network with the Bayesian regularization training algorithm (brnn). dendroTools provides the opportunity to use daily climate data and robust nonlinear functions for the analysis of climate-growth relationships. Models should thus be better adapted to the real (continuous) growth of trees and should gain in predictive capabilities. The dendroTools R package is freely available in the CRAN repository. The functionality of the package is demonstrated on two examples, one using a mean vessel area (MVA) chronology and one a traditional tree-ring width (TRW). dendroclimatology daily climate data running window nonlinear modelling tree-ring proxies climate reconstruction dendroklimatologija dnevni klimatski podatki drseče okno nelinearno modeliranje proxy podatki iz drevesnih branik rekonstrukcija klime true false true Angleški jezik Ni določen Delo ni kategorizirano 2018-04-16 15:10:25 2018-04-16 15:11:43 2022-08-16 10:00:46 0000-00-00 00:00:00 0 0 0 str. 32-39 Vol. 48 Apr. 2018 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*56:630*17:630*11 1125-7865 10.1016/j.dendro.2018.01.005 4995238 46910464 4995238.pdf 4995238.pdf 1 39B284BEC5974690B1AF8E4830A80DF2 316ed6df4125b17194f07ae8be8d6154cfabe25921ec3abd1d3bddb46e28548e 4cb5b15a-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/dda010a8-1531-486b-98b8-9ba0826c674c https://dirros.openscience.si/Dokument.php?lang=slv&id=10178 https://www.sciencedirect.com/science/article/pii/S1125786517301613?via%3Dihub 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=10177 Gozdarski inštitut Slovenije 0 0 0
