Editorial Work


  • R-package tidyfun:
    Data wrangling and exploratory analysis for functional data.
  • Co-author R-package refund:
    pffr(): Penalized additive regression for functional and scalar covariates and functional responses.
  • R-package spikeSlabGAM:
    Bayesian variable selection, model choice, and regularized estimation for (spatial) generalized additive mixed regression models via SSVS (stochastic search variable selection) with spike-and-slab priors.
  • R-package amer:
    Using lme4 to fit generalized additive mixed models. (This package was retired form CRAN since newer versions of lme4 (>0.999375-42) no longer offer a compatible interface.)
  • R-package negspline:
    Locally adaptive Bayesian P-Splines with Normal-Exponential-Gamma priors for Gaussian, Binomial and Poisson responses. package source, Windows binary
  • R-package RLRsim:
    implementing exact (Restricted) Likelihood Ratio Tests for variance components and nonparametric terms, with interfaces for models fit with nlme::lme(), lme4::lmer(), mgcv::gamm() or SemiPar:spm().
  • Co-author R-package pammtools:
    Piece-wise exponential additive mixed model tools.
  • Contributions to R-package dlnm:
    Functions for distributed lag linear and non-linear models.
