| Sep 13, 2013 at 19:21 | comment | added | zkurtz | Keep in mind that i.i.d. is two separate assumptions. The first is 'independent'. The second is 'identically distributed'. You seem to be suggesting that the observations are not 'identically distributed'. This should not affect the answers provided so far, as we can still assume that all the observations are from one big mixture of distributions. But if you think that the observations are not independent, that is a much different and potentially more difficult issue. | |

Added last paragraph to point to i.i.d requirement of CLT as possible point of failure of the method.

| Sep 12, 2013 at 23:06 | comment | added | FairMiles | And why do you think that the permutation test should be different? (if both groups have a similarly non-normal distribution) | |

| Sep 12, 2013 at 21:42 | comment | added | Alecos Papadopoulos | How does it happen that both the minimum value and the median of your data is zero? | |
