but I just wanted to make entirely sure that it is correct. I want to find one-step ahead forecast errors for my data after estimating a DSGE. I have been using the filtered variable in oo_.FilteredVariables.VARNAME and removing the first observation from that series. Is this correct or is the last value actually the forecast for time T+1, in which case I should be removing that?

Thanks.
