dynare_gui_.stoch_simul.filter{num,4}='Uses a bandpass filter before computing moments. The passband is set to a periodicity of HIGHEST_PERIODICITY to LOWEST_PERIODICITY, e.g. 6 to 32 quarters if the model frequency is quarterly. Default: [6,32].';
dynare_gui_.stoch_simul.filter{num,4}='When computing filtered theoretical moments (with either option hp_filter or option bandpass_filter), this option governs the number of points in the grid for the discrete Inverse Fast Fourier Transform. It may be necessary to increase it for highly autocorrelated processes.';
