ALL MODELS ARE WRONG – BUT WHICH ARE USEFUL?
Volker Kraft, PhD, Senior Academic Ambassador for JMP in Europe, Germany
You have a business or research question, you’ve collected or found appropriate data, and you are ready to analyze. But which analytical methods should you try? And how will you choose a final – hopefully the most useful – model? In this seminar, we will look at several data scenarios and discuss modeling options and a framework for comparison. We will look at how different questions or goals affect the modeling choices we make (Predict? Explain? Find associations?). Models covered will include traditional methods like (penalized) regression, structural equation modeling or tree-based models, as well as unsupervised and supervised machine-learning tools like clustering, neural networks or support vector machines. Comparison techniques will include residual analysis, comparing fit statistics and cross-validation. In order to support interworking with other software, we will also cover (briefly) how to import data into JMP and how to export model scoring code (e.g. as C, Python or SAS code). We will also show options to share results and visualizations from the model building and assessment phases. No prior familiarity with JMP is required. All workshop content will be shared with the participants.
Volker Kraft is Senior Academic Ambassador for JMP in Europe, fostering and supporting the use of JMP in teaching and research. He holds a Ph.D. in Electrical Engineering (University Bochum, Germany), and used statistical methods extensively in his research in psychoacoustics and speech communication. In later positions at Vodafone and Voxeo he developed a passion for customer advocacy, developing and supporting programmes to foster the effective use of software in business. Drawing on this experience and the success of JMP's Academic Program globally, Volker is charged with enabling teachers, faculty and students in Europe who are interested in JMP to get the most from the software.
