...s not changed, perhaps this wording can be massaged for clarity? The other issue, which I admit is likely a problem with my intuition, but which I don't think I'm alone in having, is that even if I can't have a 0x0 matrix (which is what I'd prefer) I would have expected/preferred a 1x0 matrix, the reasoning being that if we must avoid a 0x0 return value, we would do the minimum required to avoid, which is to not ignore the first length 0 vector, to ensure a non-zero-extent matrix, but then ignore the remaining ones as they contain information for 0 new rows. Of course I can pro...

Hello, Is there a package that implements the Cochrane-Orcutt itterative procedure for dealing with autocorrelation in a regression model?

...I prefer to have it in the form \dot{s_i}, but \partial s_i/\partial t would be O.K. In the graphics demo I cannot find either a dot or a partial equivalent.
