Dear all:
In estimation, I added the bayesian_irf but couldnot find the oo_.PosteriorIRF.dsge after estimation.
The code is written by jpfeifer for SW(2007).
estimation(optim=(‘MaxIter’,200),datafile=usmodel_data,mode_compute=0,mode_file=usmodel_mode,first_obs=71,presample=4,lik_init=2,prefilter=0,mh_replic=0,mh_nblocks=2,mh_jscale=0.20,mh_drop=0.2,bayesian_irf,irf=10,conditional_variance_decomposition=[1 4]);
Solved,the mh_replic shouldnot be 0. Sorry to bother
