Being an RStatsnewbie, I’ve spent the last 3 hours going through various ANOVA exercises. Unfortunately, everyone I’ve seen uses 1 outcome variable and 1 or 2 grouping/categorical variables.
For example, I have no issues with:
model1 = aov(bdi_total, ~ group.factor, data = dat1) TukeyHSD(model1)
However, I have more than 1 outcome variable.
group.factor = 3 (HC, FM, CLBP)
outcome variables = 3 (bdi_total, pdi_total, psqi_total)
All I want to do right now is to test whether for a group difference on the 3 outcome variables at one time. I know the answer will no be overly complicated, but I honestly cannot find an appropriate example.
