My data set has some missing values for some variables. When I do correlation, using the drop down menus (view and then correlation matrix), I notice that gretl reports a correlation matrix excluding all cases with any missing values for any of the variables.
I don't think that's correct. Notice that in the dialog window
there's a tick box saying "ensure uniform sample". And the results
differ depending on whether you tick the box or not.
However, at the top of the result printout there's the line "using obs x to y", insinuating that the same sample applies to all, even if the tick box wasn't active. So that seems to be misleading, and I guess that printout could be improved (or perhaps omitted).
cheers
