Hi Knut, Knut> Unfortunately, a non-significant test is merely Knut> non-conclusive (Popper KR, 1979), so one would have to test for Knut> equivalence, e.g., as TOST (two one-sided tests).
Knut> As to whether you can do a Lilliefors test for several groups, Knut> that depends entirely on your ability to understand what the Knut> underlying question would be (see Adams D 1979) Could you please provide more information on the Popper and Adams references you cite above? While I'm fairly certain that Popper 1979 is: Popper, Karl. Objective knowledge: an evolutionary approach. Oxford: Oxford University Press; 1979, I've had a bit of trouble searching for the Adams reference. It appears that Douglas Adams published "The Hitchhiker's Guide to the Galaxy" in 1979, and as a result of that work's popularity there's almost no hope of using a general search engine to find a different "Adams D 1979". On the other hand, the context of the citation: Knut> that depends entirely on your ability to understand what the Knut> underlying question would be (see Adams D 1979) leads me to suspect that you intended to cite The Hitchhikker's Guide.
