Hi, Just wanted to share 2 ideas about gretl's menu: 1. why does the <Rank Correlation> command come under the <Model -> Robust Estimation> menu ? It seems a little bit counterintuitive, doesn't it? correlation is much more descriptive rather than a model. 2. should the <Variable> menu switch to active even though 2 (or more) variables are selected in gretl's main window, shouldn't it? Indeed, a lot of its sub-menus (summary statistics, tests, plots,...) do make sens for a multiple variable choice as well. cheers, artur
