Re: [R] Help re. Fitting non-linear dynamic model to time series data

Hey, read and follow the posting guide -- go through a tutorial or two, post some code and data, perhaps. Also check out CRAN's time series task view here: http://cran.r-project.org/web/views/TimeSeries.html. You might also try stats.stackexchange.com , as this seems to have more to do with statis

[R] Help re. Fitting non-linear dynamic model to time series data

Hey I'm trying to fit the non-linear dynamical model as shown in the image to some time series data. The idea is also to utilize k-fold cross validation to estimate the prediction error. The term Po will be assumed to be constant over a certain timer period and will have to be estimated for eac
