This document integrates lecture notes for a one year graduate level course with computer programs that illus-
trate and apply themethods that are studied. The immediate availability of executable (andmodifiable) example
programs when using the PDF version of the document is a distinguishing feature of these notes. If printed, the
document is a somewhat terse approximation to a textbook. These notes are not intended to be a perfect substi-
tute for a printed textbook. If you are a student of mine, please note that last sentence carefully. There are many
good textbooks available. Students taking my courses should read the appropriate sections from at least one of
the following books (or other textbooks with similar level and content)
• Cameron, A.C. and P.K. Trivedi,Microeconometrics -Methods and Applications
• Davidson, R. and J.G.MacKinnon, Econometric Theory andMethods
• Gallant, A.R., An Introduction to Econometric Theory
• Hamilton, J.D., Time Series Analysis
