I'm interested in the analysis of time series data, such as EEG data, gaze data, or pupil dilation. For these analysis I prefer Generalized Additive Mixed Modeling (GAMM) as implemented in the R package mgcv (Wood, 2006; 2011), which is a nonlinear regression method.

R package itsadug

We've combined several functions that facilitate the statistical analysis with GAMMs in an R package itsadug, which is now available on CRAN. The package includes functions for model comparisons, visualization of nonlinear interactions, and inspection of the residuals.

R package prepre

We're also working on a package with functions that facilitate the preprocessing of pupil dilation data in R.
