Dear all,
I'm using the MIXED procedure in SAS and I have encountered a difficulty with fixed-effects testing since the test result depends on the method used. A factor is found significant with the Kenward-Roger method whereas it is found non-significant with the Satterthwaite method. I know this is a classical problem but I don't know enough things about these methods to be able to know which one I should rely on. Could anyone provide me some references or websites, or maybe a simple advice if the situation is actually simple?
Thanks a lot for your time,
Greetings,
