Re: [Gretl-users] Different Behavior Script and GUI

I would make a note respective the different behavior of the command "setobs n 1:1 --stacked-cross-section" by comparison with the appropriate functionality in the GUI. I wouldn't say it's a mistake, but it evokes some confusion. Suppose you have a dataset "Umsatz_Panel.txt", which contains the sales of i =4 units over t = 2 periods, for example: 1980 2110 2200 2312 2455 2380 4200 4560 Opening the file in the GUI you choose the data-structure "panel" and then "gestapelte Querschnitte" (stacked cross-sectional). The result will be the following: 1:1 1980 1:2 2110 1:3 2200 1:4 2312 2:1 2455 2:2 2380 2:3 4200 2:4 4560 That looks good.and the representation of the identifier has the format "t:i" as expected (because the first staple of cross-sectional data belongs to the period 1 etc.). If you open the file "Umsatz_Panel.txt" in a script with the commands: open "Umsatz_Panel.txt" setobs 4 1:1 --stacked-cross-section then you get the result 1:1 1980 1:2 2455 2:1 2110 2:2 2380 3:1 2200 3:2 4200 4:1 2312 4:2 4560 This is not the same representation as in the GUI, Gretl has changed the format "t:i" into "i:t" !! I know, that "i:t" is the preferred and standard representation for panel data in Gretl. If you store the above representation "t:i" (received over the GUI) in a gdt-file and load this again, you will then get the same result, will say the representation "i:t". First I was a little bit confused concerning the different behavior in the GUI and in the script. But i think it should work identically !! In respect of the command "setobs n 1:1 --stacked-time-series" the behavior is the same as in the GUI !
