Re: [Gretl-users] sub-sampling panel data to time series

Hi, I am trying to run restrict command on time series from panel sub-sample, but I got the message "Can't do: the current data set is different from the one on which the reference model was estimated dataset is subsampled, model is not." However, I could get the result when I copy the sub-sample into new file although some missing values still exist. Is this the expected behavior? How to make restrict command works in this sub-sample? Thank you, Yuniarto Hadiwibowo <script> open paneldata #Panel# panel rd 0 rf restrict b2=1 end restrict #Individual# loop i=1..4 --quiet smpl code=$i --restrict --replace printf "\n\nCode $i\n" ols rd 0 rf --robust restrict b2=1 end restrict end loop </script> ----- Original Message ---- From: Sven Schreiber <svetosch(a)gmx.net&gt; To: Gretl list <gretl-users(a)lists.wfu.edu&gt; Sent: Thu, December 17, 2009 9:23:23 PM Subject: Re: [Gretl-users] sub-sampling panel data Allin, I'm not sure I understand... Allin Cottrell schrieb: ok, so it's not really a balanced panel then in the usual sense of the term, right? so that sounds to me like --balanced doesn't really give you a balanced panel, it "just" sets equal matrix dimensions. I would have expected that --balanced does something like finding the least common denominator (wich may involve discarding lots of observations of course). But I admit I haven't read the documentation... feel free to tell me that I should do that first. cheers, sven
