{title:Description}

{pstd}
Stata has a suite of commands for fitting, forecasting, interpreting, and
performing inference on vector error-correction models with cointegrating
variables (VECMs).  After fitting a VECM, the {cmd:irf} commands can be used
to obtain impulse-response functions (IRFs) and forecast-error variance
decompositions (FEVDs).  The table below describes the available commands.
