[Gretl-users] Time series detrend deseasonality

Hi I would like to to do following steps with gretl if possible: 1. from a time series I have, I would like to remove trend and seasonality (equation parameters should be accessible) I expect a sinus similar wave for seasonality eq. and a linear eq. for trend (I do not know if I can define this) 2. after removing these two "things" I would like to take the rest (the error), plot an histogram and with Maximum Likelihood extract parameters of my density fct ... Possible ? Can you give me some hints ...? I will appreciate. Thanks GiPO _________________________________________________________________ Show them the way!
