IRF stands for impulse-response function; FEVD stands for forecast-error 
variance decomposition.

{opt irf} can be used only after {helpb var}, {helpb svar}, or {helpb vec}. {p_end}


{title:Description}

{pstd}
{opt irf} creates and manipulates IRF files that contain estimates of the
impulse-response functions (IRFs) and forecast-error variance decompositions
(FEVDs) created after estimation by {helpb var}, {helpb svar}, or {helpb vec}.

{pstd}
See {bf:[TS] irf} and {bf:[TS] irf create} for more about interpreting and
analyzing IRFs and FEVDs.
