I have a session with a panel data sample. I run smpl --no-missing Xlist to restrict the sample. Then I go to the GUI / Sample / Make current subsample permanent I get a warning whether I really want to proceed, I select "yes" and I get gretl: error "Command has insufficient arguments". Any ideas why? -- Alecos Papadopoulos PhD Affiliate Researcher Dpt of Economics, Athens University of Economics and Business Foundation for Economic and Industrial Research (IOBE) web: alecospapadopoulos.wordpress.com/ ORCID:0000-0003-2441-4550
