[Gretl-users] Iterated moving average

Hello all, I'm still new to time-series analysis, and I have a question. I am confused about what process to use in order to create an iterated, moving-average filter for my time series data. It needs to be smoothed by 3 iterations of a filter with a width of 30 days (my times series is monthly). Should I use the simple moving average function for this? Thanks in advance! -- Regards, Peter Krembs Oakland, CA USA 510.285.7098
