Hi Sorry for this stream of emails - you may ignore the previous two today (and this one too actually) as I cleared out now how we will link the different priors to the individual parameters and their individual sub-period life-spans in calculation of the posterior, as stated under Parameters and Sub-Samples on the EstimationModule wiki page.

Re: [DynareDev] Proposed specification for estimation functions

One issue about the design is, are the priors going to be dependent on the individual parameters and linked to their lifespans (from start to end of each period, all the way through), or, after the initial estimation step, priors will be dependent and related to the common estimation periods - as I understand it is the latter - and e.g. the posteriors from the previous (common) sub-sample estimation will become priors for the next - are those correct views?

Dear Michel: Attached is my revised documentation for the Dynare interface of SWZ. Feel free to expand or modify it. Two more things. 1) The request for the Atlanta Fed's commitment to Dynare's membership is moving forward. I'm awaiting for an official answer from the financial planning department here. 2) Perhaps we can arrange Houton to come to the Atlanta fed for a few things to wrap up the SWZ stuff. January and February can be busy for me as I have to help recruiting for both institutions (Fed and Emory). I wonder if some time in March is good for Houton. If not, we can certainly have Houton visiting earlier. I'm just stating my preference and do not want to rule out any particular month. Hope all is well with you and your family. Merry Christmas, Tao
