| Nov 4, 2014 at 15:24 | comment | added | Jacques Wainer | As far as I understand from the paper, Welch U is not the usual Welch-Aspin - it does not use the Welch–Satterthwaite equation for the degrees of freedom, but a formula that has a difference of the cube and the square of the sample size. | |
| Nov 4, 2014 at 13:51 | comment | added | Silverfish | I appreciate the citations! For clarification, is the "Welch U" being referred to, the same test also known as the "Welch t" or "Welch-Aspin t" or (as I perhaps impropery called it in the question) "t test with Welch correction"? | |
