title: 'rbreak: Restricted Structural Change Models'
version: 1.0.7
doi: 10.32614/CRAN.package.rbreak
abstract: 'Methods for detecting structural breaks and estimating break locations
  for linear multiple regression models under general linear restrictions on the coefficient
  vector. Restrictions can be within regimes, across regimes, or both, and are supported
  in two forms: an affine parameterization (Form A: delta = S*theta + s) and explicit
  linear constraints (Form B: R*delta = r). Provides break date estimation with confidence
  intervals, a restricted sup-F test for the null of no structural change, simulation
  of critical values by Monte Carlo, and a bootstrap restart procedure to reduce the
  risk of convergence to spurious local optima. Also implements a generalized regression
  tree (linear model tree) procedure where each leaf contains a linear regression
  model rather than a local average. Reference: Perron, P., and Qu, Z. (2006). ''Estimating
  Restricted Structural Change Models.'' Journal of Econometrics, 134(2), 373-399.
