- pflats 13y agoThe author claims to have done that to account for the relative age differences between the women (generally younger models) and the men (generally older "successful" men) featured in the magazine. If that is the case (and not just an excuse) then you might expect a bearded man to be of the same generation as a wide-skirted woman that appeared 21 years earlier. Even if you didn't shift the graphs, though, the data would still be striking. It'd likely remind me of a predator-prey graph (e.g. http://www2.estrellamountain.edu/faculty/farabee/biobk/graphpred.gif http://www2.estrellamountain.edu/faculty/farabee/biobk/graph... ) which is "easily" modeled with differential equations.
- teej 13y agoThis is a completely valid statistical approach. The author isn't hiding anything, the graph is clearly labeled. http://en.m.wikipedia.org/wiki/Cross-correlation http://en.m.wikipedia.org/wiki/Cross-correlation
