Fellow gretl users,
Artur Tarassow recently drew my attention to a minor bug in the roc (receiver operating
characteristics) function package that I wrote a while ago. An error was generated when
only 2 predicted series or roc curves were being compared. I've now fixed that, and
uploaded a new version (1.01) to the gretl server. Please update your installations
Thanks for spotting this, Artur!
