%description
Methods for detecting, estimating, and conducting inference on multiple
structural breaks in a linear system of equations, such as multivariate
linear regressions, seemingly unrelated regressions, vector
autoregressions, and network vector autoregressions. Breaks can occur in
the regression coefficients, the covariance matrix of the errors, or both,
and can be restricted to a subset of the coefficients. The main function,
sysbreak(), returns the number of breaks detected and confidence intervals
for the break dates and for the regression coefficients. A separate
function ordbreak() estimates ordered breaks, in which a break in one
subset of equations occurs before a break in another. Specialized
functions for vector autoregressions varbreak() and network vector
autoregressions netbreak() are also provided. Reference: Qu, Z., and
Perron, P. (2007). 'Estimating and Testing Structural Changes in
Multivariate Regressions.' Econometrica, 75(2), 459-502.
