sens2 function

Calculate Mean Sensitivity on Series with a Trend

This function calculates mean sensitivity of a raw or detrended ring-width series. UTF-8

sens2(x)

Arguments

• x: a numeric vector containing the series

Details

This calculates mean sensitivity according to Eq. 2 in Biondi and Qeadan (2008). This is a measure of sensitivity in dendrochronology that is typically used in the presence of a trend. However, note that mean sensitivity is not a robust statistic and should rarely, if ever, be used (Bunn et al. 2013).

Returns

the mean sensitivity.
