The lyapunov exponent part of Funfits is semi-available, but only for Windows. Doug Nychka and I, who wrote that part of Funfits, started trying to make it a CRANworthy package but never got it done. I've just linked it to my web page (www.eeb.cornell.edu/Ellner); follow the Software link on that page and get LENNS.zip. Steve

"Frozen" package Funfits was able to. Although its succesor package is Fields, it has not lyapunov exponent calculations. You can get funfits from : http://www.cgd.ucar.edu/stats/Software/Funfits/index.shtml I haven't got the statistical or programming knowledge to revise that code, if you are able to I would be keen to know of any updates. Cheers, Angel
