the direction is : stoch_simul(order=1,hp_filter=100, periods=2100);

however matlab give me it as follows when i run dynare a.mod

ERROR: stoch_simul: HP filter is not yet implemented when computing empirical simulations

??? Error using ==> dynare at 96

DYNARE: preprocessing failed

how to deal with this problem?

2

I am duplicating one model economy with dynare, I got exactly the same policy function, however the standard error of each variable is much bigger than the results in the book. Will the filter matter?

3

why do we need the filters in dynare if the model economy is just fluctuating near the steady state?
