Dear Mr. Doan,
A recent paper Murasawa (2016) "The Beveridge-Nelson Decomposition of Mixed-Frequency Series: An Application to Simultaneous Measurement of Classical and Deviation Cycles", Empirical Economics
Implements a gibbs sampler to deal with mixed frequency data.
Ox code and data are available from the authors website at:
http://ymurasawa.web.fc2.com/research.html
It would be very interesting to see this procedure implemented in RATS
Mixed-frequency series, Beveridge–Nelson decomposition
Re: Mixed-frequency series, Beveridge–Nelson decomposition
Unfortunately, while the model might seem interesting, the results are rather disappointing---on Figure 4, the "natural" rates are effectively reproducing the data.
