sens1: Calculate Mean Sensitivity

Description

This function calculates mean sensitivity of a detrended ring-width series.

Usage

sens1(x)

Arguments

x

a numeric vector containing the series

Value

• the mean sensitivity.

Details

This calculates mean sensitivity according to Eq. 1 in Biondi and Qeadan (2008). This is the standard measure of sensitivity in dendrochronology and is typically calculated on detrended series. Users unfamiliar with sensitivity in tree-ring data should see Cook and Kairiukstis (1990) and Fritts (2001) for further details.
