ModelArray is a memory-efficient R package for statistical analysis of fixel data. Its features include:

  • Easy to use: set up your statistical analysis with just several lines of codes;
  • Low memory requirement, even for large datasets;
  • Supporting linear and nonlinear modeling: At present, ModelArray supports linear models as well as generalized additive models (GAM) with and without penalized splines, which are particularly useful for studying nonlinear effects in lifespan data. ModelArray is also extensible to more models.
