Research Seminar - Rudolf Debelak


We are pleased to announce the upcoming Research Seminar on May 26, 2023.

The Institute for Statistics and Mathematics is pleased to invite you to the next research seminar, taking place on campus:

Rudolf Debelak (Department of Psychology, University of Zurich):
Sample Size Planning for Latent Variable Models: Classical Approaches and Recent Developments
Friday, May 26, 2023, 10:30 am, Room D4.0.127

Abstract: Planning an empirical study in the social sciences involves an estimation of the sample size that is necessary to detect a particular effect. In this talk, I discuss methods to address the problem of sample size estimation for latent variable models that are widely used in psychology and related fields. An initial approach involves classical methods of power analysis, which allow an analytical estimation of sample size. A drawback of these approaches is that they are computationally expensive under some realistic scenarios. As an alternative, a second approach is presented that uses machine learning models to estimate sample size. This second approach was found to lead to promising results under realistic conditions in a variety of simulation studies. All of the presented approaches are available in R packages.

We aim to stream all on-campus talks via Zoom. A direct link to the stream will be posted on our website.
