Suppose we have a time-series $x(t_i)$ at discrete times $t_i$ and we want to estimate the parameters of an underlying SDE corresponding to this time-series:   

$$dx_t = f(x_t,\theta)dt + \sigma(x_t,\theta)dB_t$$ I

I have read that there exists a lot of different numerical methods to approach this problem, but I have not found a comprehensive and comparative survey about this problem.

1.What is the best method (according to the type of data/model) ?

2.Is there a Python or Matlab toolbox doing the job ? I have had a look at SDE_toolbox for Matlab (http://sourceforge.net/projects/sdetoolbox/?source=dlp) but it is not clear to me how to use it, so it would be appreciated to provide an example.

I think it can be useful to have an overview of this topic since it may be interesting for many people.

  Thank you.

Parameter estimation for stochastic differential equation from discrete observations
