Thanks for the references. I had read those article and Jin's thesis
also detailing the models. However all these publications dont
provide any background to the parameter estimation method. There are
no details that how the input data is used to estimate parameters
which are then used in the models. There should be some equations,
some method which is used.

Can anyone help?
