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

dendroTools (version 1.0.0)

Linear and Nonlinear Methods for Analyzing Dendroclimatological Data

Description

Provides novel dendroclimatological methods, primarily used by the Tree-ring research community. There are two 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. The second one is compare_methods(), which effectively compares several linear and nonlinear regression algorithms.
