[Gretl-users] using some test commands with matrix input (instead of series)

Hi, I've come across the (minor) problem that I wanted to test a vector of data observations for following a certain distribution. There was no statistical problem, but I had to set up a "dummy" workfile with "nulldata" and convert the vector to a series to be able to use the "normtest" command. But since "nulldata" isn't so easy to use or not allowed in loops and/or functions, this caused some complications. So I wanted to ask if it's also possible to run such tests on vectors/matrices, instead of series in workfiles. Besides "normtest" another candidate might be "difftest", and probably some others, too. thanks, sven
