Comment on "Reliability of the 0-1 test for chaos".
Recently Hu, Tung, Gao, and Cao [Phys. Rev. E 72, 056207 (2005)] investigated the 0-1 test for chaos. By looking at random data and at data stemming from the one-dimensional logistic map they concluded that the test is unreliable. We explain why their criticism is unfounded.
