...es in R allowing to find breakpoints assuming linear model. However, I would like to fit a periodic time series with a non linear (periodic) model, and I was wondering how I could find breakpoints for this model in R. Is it even possible ? My model is an asymmetric gaussian fitting (cf http://www.nateko.lu.se/personal/Lars.Eklundh/Institutionssida/IEEE_TGRS_timesat.pdf) with a linear-time-dependant amplitude (I am fitting this model over the whole time series). *My ideas * 1) I guess I am more interested in the breakpoints of the "amplitude" of my periodic function, so that I could ass...
