-xtunitroot- has a help file and a manual entry. That's the place to look for guidance, not the web.
In terms of giving guidance, you don't give us the code you typed. That would help -xt- experts.

I'm trying to run stata's xtunitroot ips command on a large unbalanced panel (N=10,000, T ranges from 52 to 292), and there are no missing observations. The program runs, but the output is blank. I get the normal output with a table where test statistics should be, but all the statistics are missing and it says (Not available) where the Fixed-N exact critical values should be reported. I've scoured the web for others with this problem, but there doesn't seem to be much guidance on xtunitroot.
