This two-day course is designed for persons interested in multivariable regression analysis of univariate responses, in developing, validating, and graphically describing multivariable predictive models. The first part of the course presents the following elements of multivariable predictive modeling for a single response variable: using regression splines to relax linearity assumptions, perils of variable selection and overfitting, where to spend degrees of freedom, shrinkage, imputation of missing data, data reduction, and interaction surfaces. Then a default overall modeling strategy will be described. This is followed by methods for graphically understanding models (e.g., using nomograms) and using re-sampling to estimate a model's likely performance on new data. Then the freely available S-Plus Design library will be overviewed. Design facilitates most of the steps of the modeling process. Next, statistical methods related to binary logistic models will be covered. Three of the following case studies will be presented: an exploration of voting tendencies over U.S. counties in the 1992 presidential election, an interactive exploration of the survival status of Titanic passengers, an interactive case study in developing a survival time model, and a case study in Cox regression. In the hands-on computer lab students will develop, validate, and graphically describe multivariable regression models themselves. This short course will also survey the advantages of modeling in randomized trials. The methods covered in this course will apply to almost any regression model, including ordinary least squares, logistic regression models, and survival models.
