Welch versus Satterthwaith (PR#2111)
This is not a bug report but didn't see another way to ask a question.
For the approximate t-test assuming unequal variances, the R docs cite
Welch's method for the df of the approximating distribution.
I have several methods books, and they all uses Satterthwaite's method.
Why does R use Welch's method where can I learn about Welch's method?
Sincerely,
