%description
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:
