That would then however not be an exact result anymore of course, though. | |
| Mar 11 at 16:25 | comment | added | Richard Hardy | The case with different variances seems to require knowledge of the variances, as otherwise the test statistic is infeasible. Is that right? (Also, I have simplified the question relative to the referenced application, so just allowing the variances to be different is still not enough.) | |
