The source code of the package tvReg is publicly available for download from the Comprehensive
R Archive Network. The five basic functions in this package are the tvLM, tvAR, tvSURE, tvVAR and tvIRF, which cover a large range of semiparametric models with time-varying coefficients. Moreover, this package provides methods for the graphical display of results, extraction of the residuals and fitted values, bandwidth selection, nonparametric estimation of the time-varying variance-covariance matrix of the error term, and two estimation procedures: the time-varying ordinary least squares implemented in the tvOLS method and the time-varying generalised least squares in the tvGLS method. Applications to risk management, portfolio management, asset management and monetary policy are used as examples of these functions usage.
