⚠️There's a newer version (1.2.14) of this package.Take me there.

dendroTools (version 1.2.11)

Linear and Nonlinear Methods for Analyzing Daily and Monthly Dendroclimatological Data

Description

Provides novel dendroclimatological methods, primarily used by the Tree-ring research community. There are four core functions. The first one is daily_response(), which finds the optimal sequence of days that are related to one or more tree-ring proxy records. Similar function is daily_response_seascorr(), which implements partial correlations in the analysis of daily response functions. For the enthusiast of monthly data, there is monthly_response() function. The last core function is compare_methods(), which effectively compares several linear and nonlinear regression algorithms on the task of climate reconstruction.
