Talk by Tom Fritzsche (University of Potsdam), Tuesday 12th, 2-4 pm
We are very happy to announce the next talk in the Recent Trends in Language Acquisition Colloquium, which will take place on Tuesday, February 12, 2 – 4 pm in IG 3.301.
Tom Fritzsche will present "Data analysis with linear mixed models: A practical example from language acquisition".
Abstract: Linear mixed-effects (LME) models have become the standard in analysing psycholinguistic and psychological data. Compared to t-tests and ANOVAs LME models offer numerous advantages but also require additional attention for specifying a model as each can (and needs to) be tailored to the structure (and the amount) of the data. Advantages and challenges will be discussed using a specific data set: Szendrői et al. (2017). The paper along with the code is available online (links below). The purpose of this presentation is to go through the analysis of this study in R and address questions regarding:
- model specification
- contrast coding
- fixed & random components
- factors & continuous predictors
- model evaluation and selection
- limits...
