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. However, note that mean sensitivity is not a robust statistic and should rarely, if ever, be used (Bunn et al. 2013).
