New features

New additive explainer additive_shap() that works for models fitted via

  • lm(),
  • glm(),
  • mgcv::gam(),
  • mgcv::bam(),
  • gam::gam(),
  • survival::coxph(),
  • survival::survreg().

The explainer uses predict(..., type = "terms"), a beautiful trick
used in fastshap::explain.lm(). The result will be identical to those returned by kernelshap() and permshap() but exponentially faster. Thanks David Watson for the great idea discussed in #130.

User visible changes

  • permshap() now returns an object of class "kernelshap" to reduce the number of redundant methods.
  • To distinguish which algorithm has generated the "kernelshap" object, the outputs of kernelshap(), permshap() (and additive_shap()) got an element "algorithm".
  • is.permshap() has been removed.
