Course Syllabus


This course will take a modern, data-analytic approach to the multiple regression model. Our coverage of the material will emphasize the ways that graphical tools can augment traditional methods for describing how the conditional distribution of a dependent variable changes along with the values of one or more independent variables. The course will examine the basic nature and assumptions of the linear regression model, diagnostic tools for detecting violations of the regression as-sumptions, and strategies for dealing with situations in which the basic assumptions are violated.
Learning Objectives

Learning Objectives

  • The goal of the course is to ensure that students understand topics and principles of applied linear models on an advanced level.
  • The course gives students an important foundation to develop and conduct their own research as well as to evaluate research of others.
Expected Learning Outcomes

Course Contents

  • Examining data
    The first session will introduce the main concepts of preparation for multivariate regression analysis. We will discuss graphical displays, data transformations, and other techniques of multi-dimensional exploratory analysis.
  • General Linear Models I: The Basics of Least Squares Regression
    The session is a review of basic linear models with an extension to multivariate regression. We will review graphical fitting, least-squares fitting, properties of least-squares estimator, statistical inference, regression models in matrix form, vector geometry and vector presentation of the regression model, the data ellipsoid and model fit.
  • General Linear Models II: Effective Presentation I
    The session will go in much more detail into topics of categorical predictors, fitted values, inter-actions and effect displays, standardization and relative importance of predictors.
  • Regression with Categorical Dependent Variables I
    This sessions will provide an understanding of limited dependent variables and problems with the OLS models; binary logit and probit models, fitted probabilities and effect displays.
  • Regression with Categorical Dependent Variables II
    This session covers ordered probit and logit models, Multinomial logit models, Generalized linear models, Poisson models for count data, Diagnostics for generalized linear models.
  • Regression diagnostics I: Unusual observations
    This session will show how to examine outliers, leverage, and influence observations; hat values and studentized residuals; and case-deletion statistics.
  • Regression Diagnostics II: Nonlinearity, Nonnormality, and Heteroskedasticity
    This session will focus on residual plots, visual and maximum likelihood methods for determining transformations, weighted least squares to adjust for nonconstant error variance, robust standard errors. It will also look at variance inflation, principle components analysis, collinearity and model selection, and ridge regression.
  • Resampling techniques for regression
    This session will introduce bootstrapping and jackknifing, as well as cross-validation.
  • Nonlinear regression
    This session will examine transformable nonlinearity, polynomial regression, orthogonal poly-nomials, and non-linear least squares.
  • Nonparametric regression I: Local polynomial regression
    This session will cover local regression (LOESS) and its fitting parameters, robust local regres-sion, and degrees of freedom in local regression, M-estimation and iteratively weighted least squares and bounded influence regression.
  • Nonparametric Regression II: Smoothing Splines
    This session will introduce the concepts of piecewise regression, cubic smoothing splines, thin plates smoothing splines, and their degrees of freedom.
  • Additive regression models (GAM) and graphical regression
    This session will look at estimation and backfitting, cross-validation for smoothing parameters, GAM for binary dependent variables, vector GAM for ordered dependent variables. It will also introduce the concepts of model checking plots, visualizing regression with more than two pre-dictors, and sequentially combining predictors.
