Allin, Two suggestions for the next version of gretl, if you deem them worthy of attention: 1. The new forecasting platform of gretl is SUPERB and allows one to carry out model estimation and forecasting without the need for any additional calculations or backtransformations. Would you consider adding similar capabilities in ARMA, i.e. making the ARMA platform look like an ARIMA platform that would, in other words, allow the user to specify the degree of differencing and let gretl take care of the rest? 2. When gretl plots a scatterplot in which zero is included in the Y range, the zero reference line is plotted nicely as a DOTTED line and this translates correctly to either a PDF or an EPS graphics file. UNFORTUNATELY when copying/pasting or saving the file as a Windows metafile, this dotted line becomes SOLID. I am sure there is a solution to this in gnuplot BUT it should not be trivial. Would you consider fixing this so one may readily copy/paste graphic files into, say, a Word document? Regards John Paravantis University of Piraeus
