The package strucchangeArmadillo was written by Marius Appel
as a fast re-implementation of certain features from strucchange.
Speedups are gained from C++ leveraging the RcppArmadillo package.
For now there is only a C++ implementation of recursive residuals.
The latest version can be installed from R-universe:
install.packages("strucchangeArmadillo", repos = "https://zeileis.R-universe.dev")
The package is available under the General Public License version 3 or version 2
