Surviving Survival AnalysisChocolate Cake Seminar Series on Statistical ApplicationsApr 15, 2013 FO 5Room 116 Let’s pretend you participate in a weight loss study. The study isn’t over yet, but you got a very luring job offer that requires you to move out of state and you cannot continue in this study. Should your data be thrown out and not used for the analysis after all since you never completed the study? The answer is “No, not at all”. The talk will explain how to model times to events (e.g., 20% excess body weight loss) in presence of dropouts. Two survival analysis techniques, KaplanMeier curve and Cox model, will be studied through SAS and SPSS applications. view

Nonpoisonous Poisson Regression at Your FingertipsChocolate Cake Seminar Series on Statistical ApplicationsMar 18, 2013 FO 5Room 116 Have you ever counted how many cars are in front of you at McDonald’s drivethru? Is it a number between zero and infinity? Well, just notice the hour of the day and you got yourself a Poisson regression. Attend the talk and learn how to model properly the relation between the number of cars and the hour of the day. You won’t be bored. We promise. Applications in SAS and SPSS will definitely keep you awake. view

Get Empowered by Power Analysis!Chocolate Cake Seminar Series on Statistical ApplicationsFeb 18, 2013 FO 5Room 116 How can you tell how many people you need for your study? Is it ten, twenty, sixty, one hundred? The number of participants should not be determined by time and budget alone. Statistical rigor, called power analysis, must be applied. The talk will expose the details with applications in SAS and other specialized softwares. view

Binary and Multinomial Logistic Regressions at WorkRIMI Brown Bag Seminar Series on Statistical ApplicationsMay 2, 2012 What if the variable you are about to model assumes only a handful of different values? Can you say it is a continuous variable and use a linear regression model? The answer is enthusiastically, “No!” The talk will explain why it is so and introduce you to appropriate regression approaches. SAS and SPSS statistical software packages will be employed. Basic knowledge of linear regression modeling will be required. There will be time for questions and discussion after the presentation. view
