What if there are four measurements but no treatment (a comparison of two trends over time)PowerPoint Presentation: Which is best? Lecture 2: Discrete choice modelsLecture 2: Discrete time logistic regression: Lecture 2: Discrete time logistic regressionOral treatment to reduce blood lead levels: Oral treatment to reduce blood lead levels Lecture 3: Introduction to longitudinal analysis and repeated measures analysisPowerPoint Presentation: Lecture 4: Clinical examples of longitudinal analysis and repeated measures analysisLecture 5: competing risks: Lecture 5: competing risksLecture 6: multi-state models: Lecture 6: multi-state modelsLecture 7: overview of multi-level models: Lecture 7: overview of multi-level modelsLecture 8: Clinical examples of multi-level models: Lecture 8: Clinical examples of multi-level models Multi-membership model Example: patients (t’s) seeing different patients (m’s)PowerPoint Presentation: Lecture 9: Discrete time multi-process modelsSemivariance: Semivariance Lecture 10: Overview of spatial analysisInterpolated map: Interpolated mapSpatial analysis: Spatial analysisNearest neighborhood analysis: Nearest neighborhood analysisClinical accessibility: Clinical accessibility Lecture 11: Selected applications using spatial analysisExamine distributions: Examine distributionsStatistically adjusted mortality rates: Statistically adjusted mortality ratesLecture 12: Overview of structural equation modeling: Lecture 12: Overview of structural equation modelingLatent variables f1 and f2 Predictors x1, x2, and x3: Latent variables f1 and f2 Predictors x1, x2, and x3Lecture 13: Growth models using structural equation models: Lecture 13: Growth models using structural equation modelsParallel growth processes: Parallel growth processesLatent class analysis: Latent class analysis Lecture 14: Advanced topics using structural equation modelsProstate specific antigen and development prostate cancer: Prostate specific antigen and development prostate cancerMultilevel latent variables: Multilevel latent variablesLecture 15: Intensive longitudinal designs : Lecture 15: Intensive longitudinal designs Urges to smoke in a smoking cessation program Participants were beeped on approximately 250 occasions on a handheld palmtop computer When beeped they answered a questionnaire on their current setting and activities, and their mood and urges to smokePowerPoint Presentation: Regulation of intimacy and disclosure in marriageCoupled trajectories: Coupled trajectories You do not have the permission to view this presentation.
