Linear Statistical Analysis I STAT 8561 Spring 2011 Computer No. 17165 Instructor: Office: Phone: E-mail: Dr. Yichuan Zhao 726, College of Education (404)413-6446 [email protected] Office Hours: Class: MW: 12:30—2:30 PM, other times by appointment TR: 2:30—3:45 PM, 329—ALC Course Description: Prerequisite: MATH4751/6751. This course serves to illustrate basic methods in linear regression and to demonstrate the power of regression methods by substantial applications. Topics included are statistical inference, multivariate normal distribution, distribution of quadratic forms, regression models, model checking, transformations to correct model inadequacies, variable selection and model building, multicollinearity, and other related topics. Text Books: Main material is from the following book. Introduction to Linear Regression Analysis, 4th edition by D. Montgomery, E. Peck and G. Vining, John Wiley & Sons, Inc. 2006. Reference Texts from the library. Course Objectives: Upon successful course completion a student will be able to… understand the concepts of linear modeling. understand the least squares estimations in a linear regression analysis. manipulate least squares estimation results on a multiple linear regression with matrix notations and operations. understand and be able to perform the inferences related the least squares estimations including correlation analysis. perform residual analysis on the fitted model. perform diagnostic checking of the fitted model, such as the lack-of-fit test. perform various transformations, such as Box-Cox transform. perform variable selection and model building procedures. understand the problem of multicollinearity in a multiple regression, and will be able to solve the multicollinearity problem. Important During the first two weeks of the semester the Department of Mathematics and Statistics checks the computer records to determine whether or not each student has met the prerequisites for this course. If you do not have the prerequisites, please inform your instructor and change to another course right away. If our computer search finds that you do not have the prerequisite, you must drop this course or you will be dropped automatically. If you do not attend class during the first two weeks you will be administratively dropped. SAS: Use of SAS is required. Assign selected problems to be done with SAS and to be turned . Tentative Course Content and Reading Material The number of weeks is used to cover the chapters are indicated in the parentheses. Chapter 1 (0.5 week) Chapter 2 (2 weeks) Chapter 3 (3 weeks) Chapter 4 (2 weeks) Chapter 5 (1.5 weeks) Chapter 8 (1 week) Chapter 9 (1.5 weeks) Chapter 10 (0.5 week) Chapter 11 (1.5 weeks) Student regulations: 1. Attendance will be taken. Attendance will give you bonus points. On the other hand the instructor may drop a student from the roll for exceeding 4 class absences. 2. The last day to withdraw from the class and receive “W” is February 25. Grading Policy: Grading will be based on tests and assignments. NO make up exam. The grade will be based on the following percentages. 40% 30% 30% Homework Mid-term Exam Final Exam Final grades will be determined as follows A 90----100 B+ 87----89 B 80----86 C+ 77-----79 C 70-----76 D 60----69 F 0-----59 Mid Exam is 02/24/11 Final Exam is 04/28/11 (Thursday) at 1:30 PM. Plagiarism: All work submitted for grading must be the student’s own work. Plagiarism will result in a score of zero on the test or paper, or dismissal from the course. Also, the Dean of Students office will be notified. Students with Disabilities: Students with disabilities needing academic accommodation should: (1) register with and provide documentation to the Office of Disability Services; (2) bring to a letter to the instructor indicating the need for accommodation and what type. This should be done during the first week of class.
