Dear Professor,

I get the following error message. Can you please help me with it?

Etimation::mcmc: One Chain mode.
Index exceeds matrix dimensions.

I use the following command

Code: Select all

estimation(nograph, datafile = DSGE, prefilter = 1, nobs=[132:135], mode_compute = 4,mh_nblocks = 0, mh_replic = 80000, mh_drop = 0.35, mh_jscale = 0.35, forecast = 4) d;

Much appreciated

You need at least 1 chain, but you set

Code: Select all

mh_nblocks = 0
