EXST7034 – Regression Techniques Fall 2005 Assignment 1 Page 1 EXST7034 : Regression Techniques HOMEWORK ASSIGNMENTS : General Information PC/NT Workstations are available in room 11 and room 48, both in the basement of the Ag. Admin. Building. Class schedules will be posted and you can use either when regular classes are not scheduled. Room 50 should become available as an open lab in a few weeks. The use of SAS is strongly encouraged. Most homework assignments can be done in two to four pages. Do not pass in raw computer printouts unless requested. If you need to reference computer output, cut out the parts you need and tape or paste them onto written homework, or write your answers on selected output pages. Do not pass in computer pages you do not need. Homework is generally due on Thursday of each week. All of the data files for this book are available on disk. The disk is included with the textbook. I will also maintain a listing of the data files on the internet at http://www.stat.lsu.edu/exstweb/statlab/datasets/NKNWData/index.html HOMEWORK ASSIGNMENT 1 Assigned: September 8, 2005 Due: September 15, 2005 20 Points – 1 point each day late Questions are from chapter one of your text, Kutner, Nachtsheim, Neter and Li (2005) or Neter, Kutner, Nachtsheim, Wasserman (1996).
