I think there may be a misunderstanding here. I open and run the following trivial Kalman script in gretl: nulldata 50 setobs 1 1 --special scalar s1 = 1 scalar s2 = 1 series y = normal() kalman obsy y obsymat 1 statemat 1 statevar s2 obsvar s1 end kalman --diffuse matrix E V S MSE G kfilter(&E, &V, &S, &MSE, &G) # optional: take a look print E V S I then save the session, either by going to /File/Session files/Save session, or by right-click in the "Icon view" window. I call the file kaltest.gretl. I then exit from gretl, restart the program, and open kaltest.gretl (e.g. under the /File/Session files menu). The matrices E, V, S, MSE and G are shown in the Icon view window. Where does your experience differ?
