JOB #1
For September 13th: Chapter 3 of W&H.
- Read and digest.
- Exercises 3.6, 3.10 and 3.11. Here 3.10 is the big one. For this you will
- Develop code -- (Matlab preferably, R/Splus is OK, C/C++ OK too) that is modular,
short and simple -- implementing the sequential learning in a general
dynamic regression DLM, rather than just the one variable/no intercept model.
The general model and its updating equations are the special case of the general
DLM with Gt set to the identity matrix: read this off the tabular summary in
Section 4.6 with that simplification.
Implement it with the discount factor specification for evolution variances
in which Wt = Ct-1(δ-1-1)
- For Exercise 3.10, you will simply apply this code in the special, simple
case of one predictor/regressor and zero intercept.
- Use this to address exercise 3.10: This essentially just
reproduces/refines
the worked example of section 3.4.2. Include in your write-up your versions
of figures 3.5-3.9.
- Hand in detailed code print-out, the figures above and comments on your experiences.
Use Latex/Tex please.
- Sept 7th class: Carlos Carvalho will hold office hours throughout the class period in
025 Old Chem, for discussion of Chapter 3 and the big-picture issues as well as
details.
- Hand-in completed assignment (in Mike W's Duke Statistics mailbox in room 211 Old Chem)
before 5pm on Tuesday 13th September.
