In statistics, particularly in experimental design, what is the difference between confounding and aliasing in 2^k factorial designs? Also how is a principal block related to the two concepts? I've been looking into the topic recently but there doesn't seem to be a clear difference between them?

  • $\begingroup$ I think that confounding and aliasing are synonyms. If you have some reference saying otherwise, please tell us. $\endgroup$ – kjetil b halvorsen Mar 28 '17 at 15:25
