Course
materials:
- Course information, assessment procedures,
etc.
- Lecture
notes. These are constantly under revision, before and after class.
- The course assumes an
undergraduate knowledge of Time Series at the level of STAT 479, and mathematics at the level
of STAT 512.
Assignments:
Obtaining
and using the R package:
- For a quick start you
can obtain R here and
install it on a PC by double-clicking on this .exe file and following the
instructions. There is a Mac version of R too; you'll need to consult the
'R home page' link below for this.
- There is a problem with
R version 2.8 which impacts us - see the notes by
S&S. But version 2.7 is fine and can be obtained here.
- What is R?
- The R home page
- An R manual
- A
brief introduction to R
Text/computing
downloads:
- Typographical errors in
the text.
- Some further (and very
useful) information about
R; see in particular the authors' R
tutorial and some of their caveats
regarding R for time series analysis.
- Datasets used in the text.
These can be saved to your own system individually, or you can download
all of them at once as data.zip.
- R code used in
the text.
- Some R functions supplied by Shumway
& Stoffer and extended and modified by me. See the notes by S&S.
You can make their (unmodified) functions available by entering a command source("http://www.stat.pitt.edu/stoffer/tsa2/Rcode/itall.R") within
any R programme.
- Further R
functions and code
unique to Chapter 6. You can make these functions available by
entering a command source("http://www.stat.pitt.edu/stoffer/tsa2/Rcode/New6/ssall.R") within
an R programme.
- Code unique to
Chapter 7.
Technical
Writing:
- The importance of
clarity of exposition, and of grammatical correctness, in technical
writing cannot be over-emphasized. The best way to determine if you
understand what you are doing is to try to write it down in a form that
another reader can understand. Some comments along these lines are
included with the course information; for
some helpful resources see "Writing Aids" on my homepage.
Code
for R examples discussed in class (some of these originated at the authors' website):
You should find it useful to download and run these R scripts before
the classes in which they are to be discussed.
