Project Instructions
SYST/STAT 664
You are required to do a semester project applying what you have learned
in this course to a analyze any data set of your own choosing. If
you are a PhD student, this is an excellent chance to do some work that
might apply directly to your dissertation. You may want to test out
a hypothesis or explore an idea in preparation for writing your dissertation
proposal. If you are a part-time student, here is a chance
to identify something related to your job to which the methods of this
course are applicable, and that might also have potential to lead to a
dissertation project. (Synergy is a very good thing!)
I have a book called Handbook of Small Data Sets, that you
may find helpful for this project. I'm willing
to lend it to interested students to browse. The data sets from this
book are available on the web. Many other interesting data sets are
available on the Web. I enjoy new and different ideas -- for
example, my PhD advisor at one time told me he had found an astrologist
who was willing to work with him to do a Bayesian evaluation study of
her
astrological predictions. Use your imagination and enjoy
yourself.
You may feel free to compare a Bayesian and a frequentist analysis on
the
same data set.
You must hand in a report on your project that:
-
Describes the problem context and the question you are asking for which
the data set provides information;
-
Describes any background information the reader needs to understand the
problem;
-
Shows summary statistics, exploratory plots, and any useful information
that will help the reader understand the data set;
-
Describes the prior distribution and likelihood function you are using
in your statistical model.
-
Describes the posterior distribution. Include summaries such as credible
intervals, hypothesis test results, triplots -- any of the techniques we
learned that will be relevant to your analysis.
-
Discusses the assumptions underlying your analysis and your justification
for those assumptions.
-
Reports any conclusions you are drawing from your analysis.
-
Describes how the conclusions depend on the assumptions you made.
I hope you will find this project an enlightening and even enjoyable way
to practice the concepts you are learning in this course.
