[Gretl-users] issue with fctstats()

Dear all, I am not sure this behavior is intended, but to me it looks some unintended behavior. In the following example one of the scalars in the vector of realized values y is zero which drives the division "(e./y)=-inf" and which affects the later sum calculation as well. I guess gretl should ignore this "-inf"-value, or do I miss anything here? <hansl> matrix y = {0; 1} matrix f = {0.5;2} matrix e = y-f eval fcstats(y,f) # MPE by hand eval e./y mat = (0.5).*sumc(100*e./y ) mat </hansl> Best, Artur
