Good morning everyone, I am looking for a package in R cran to fit a double logistic curve like this: http://en.wikipedia.org/wiki/File:Dsigmoid.png but the packages I've found are not running for my data, in particular: "phenex" package is specifical for NDVI data, "FlexParamCurve" is really interesting but it seems that id does not allow this specifical fitting. Could someone give me some advices? Thank you a lot! ______________________________________ If you reply to this email, your message will be added to the discussion below: http://r.789695.n4.nabble.com/Double-logistic-or-double-sigmoid-in-R-cran-tp4687028.html This email was sent by Phalaen (via Nabble) To receive all replies by email, subscribe to this discussion: http://r.789695.n4.nabble.com/template/NamlServlet.jtp?macro=subscribe_by_code&node=4687028&code=ci1oZWxwQHItcHJvamVjdC5vcmd8NDY4NzAyOHwtNzg0MjM1NTA4 [[alternative HTML version deleted]]
