,PREFACE
This Instructor’s Manual contains solutions to the Exercises in the Probability Primer, Chapters 2-
16 and Appendices A, B and C in Principles of Econometrics, 4th edition, by R. Carter Hill,
William E. Griffiths and Guay C. Lim (John Wiley & Sons, 2011).
There are several other resources available for both students and instructors. Full details can be
found on the Web page http://principlesofeconometrics.com/poe4/poe4.htm. These resources
include:
Answers to Selected Exercises. These answers are available to both students and
instructors. They are shortened versions of the solutions in this Manual for exercises that
are marked in POE4 with a *.
Supplementary computer handbooks designed for students to learn software at the same
time as they are using Principles of Econometrics to learn econometrics. These
handbooks are available for the following software packages:
EViews
Stata
GRETL
Excel
SAS
Data files for all text examples and exercises. The following types of files are available:
Data definition files (*.def) are text files containing variable names, definitions
and summary statistics.
Text files (*.dat) containing only data. Variable names are in *.def files.
EViews workfiles (*.wf1) compatible with EViews Versions 6 or 7.
Stata data sets (*.dta) readable using Stata Version 9 or later.
Excel spreadheets (*.xlsx) for Excel 2007 or 2010.
GRETL data sets (*.gdt).
SAS data sets (*.sas7bdat) compatible with SAS Version 7 or later.
