The parametric bootstrap joint (pbj) methods are designed for voxel-wise and cluster-extent inference and include semi-PBJ (sPBJ) inference that is robust to variance misspecification using an estimating equations approach. The package is designed for neuroimaging data and allows for input and output of neuroimaging data.

Ongoing projects

The pbj package is in alpha stage as many features are still being added.

  • A graphical user interface
  • Semiparametric multidimensional inference (F-tests)
  • Semiparametric longitudinal multidimensional inference (F-test in repeated measurements models)
  • Semiparametric confidence set inference
  • Effect size based inference
  • Nonparametric bootstrap-based inference
