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. Users unfamiliar with sensitivity in tree-ring data should see Cook and Kairiukstis (1990) and Fritts (2001) for further details.
