[Gretl-users] Tests for Random Residuals

Good Morning, About two months ago when I first started working with Gretl I asked if Gretl has tests for randomness of model residuals (accessible from either the GUI or the command line). I got a number of fairly non-specific responses like "look at the documentation" and "look at the menus on the windows". Well, after two months of working with Gretl I am now a hardened veteran and ready to ask the question again: The only mention of a test for randomness I can find is the non-parametric runs test. Can Gretl do a Ljung-Box test (or some other test I am not familiar with) of the randomness of residuals? Thanks in advance for any advice you may offer. Tom
