Hi all
This is a new topic. In the future, please don't
just reply within an
existing thread (even if you change the subject line), but send a fresh
email message to the list.
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
