Textbook: Introduction to Regression Analysis , Revised & updated Ed. (2010), by M. Golberg and H. Cho, Wessex Institute of Technology, Southampton, UK.


Description of the Course: This course provides both foundation and applied perspectives of regression analysis, as a gateway to understanding statistical modeling. The emphasis will be placed on the theoretical foundation, statistical rationale, the investigation of the relationship among variables in a data set, and further advanced topics, models and recent developments. Among topics to be covered will be


                1.         Basic concepts and background - Probability space, random variables (or vectors), normal distribution and related distributions, estimation, testing hypothesis, (matrix algebra).

                2.         Simple linear regression - Regression overview, least-squares method, Gauss-Markov theorem, ANOVA approach, lack of fit test, assessing model validity, transformation.

                3.         Multiple regression analysis - Matrix approach, multiple linear regression models, quality fit and prediction, HAT matrix, extra sum of squares principles.

                4.         Residual analysis, diagnostics and remedies - Analysis of residuals, plotting residuals, PRESS statistics, transformation, correlated errors.

                5.         Further models in regression - Polynomial models, indicator variables, modeling categorical variables, logistic regression, generalized linear model, selecting models, multicollinearity, ridge regression, other alternatives.

                6.         Selecting and criteria of regressions - Model misspecification, predictive criteria, methods of selecting models.


Homework: All homework assignments will be given in class and expected to turn in on time. No late homework will be accepted. Some of the problems will be discussed in class.


Exams: Two midterm tests will be most likely on 5th/6th and 10th/11th week and a final exam will be given according to the university calendars and schedules.


Grading:    The course grade is based upon the following: (1) homework assignments 20% (2) two mid-semester exams 25% each, and (3) a final exam 30%.  Grade Scale: A-A: 85% or above, B-B: 75% or above, C-C: 65% or above, D-D: 55% or above, F: Below 55%.
