hi, I'm puzzled cause when i did anova with the help of R and StatView, i didn't get same results ! Indeed, the model is aov(Vol~apoe*hta*Age) where ope and hta are 2 levels factor, and Age is quantitativ data. We observed same results concerning : Residual interaction apoe:hta:Age and other outputs are different. Does anyone have an idea ? -- Delcroix Nicolas - GIN - CNRS UMR 6095 - CEA LRC 13V GIP CYCERON BP.5229 14074 CAEN Cedex tel: 02 31 47 02 79 fax: 02 31 47 02 22 Email: delcroix at cyceron.fr -------------- next part -------------- An HTML attachment was scrubbed...
