Hi, Whit, Thanks for your reply. I will try out all possibilities and get back to you. This is still my first try. My skills in c++ are at the...

Update: just did a run with simulated dataset instead of the real ones. I also restricted in the simulation that the 2 parameters in the original model must be equal....

Now I did a simulation study without calling other computer program. But the acceptance ratio is still 0. The functions needed for this example is in a package repository at...

I am not sure where it went wrong. Optimization produced sensible results but are quite far away from the true values. Is it possible that it is because there are...

Yes, the model and the result should be reproducible from the above code. The R folder in that github link contains the functions used. The initial values are from the...

No, I haven't yet. Last time I checked there was no suport for ODE integrator yet. But I see now they have a working code brunch. However I need time...

Hi Whit, I have ran the model in STAN and the chains freeze very often. I asked in stan user mailing list [here](https://groups.google.com/forum/#!topic/stan-users/dIx5E_yrp6c) where I got an answer related to...
