First pardon my limited knowledge of statistics, which I learned
mostly thru SAS programming.
Here is the question: We have two scale systems used to measure the
patients for the treatment. One is called SelfCare, like bath, groom
etc. And the other one is called Mobility, like transfer2bed,
transfter2chair etc. The scale ranges from 1 to 7, with 1 as lowest
and 7 as highest. Both systems tracks the prescores and postscores. I
heard of multivariate analysis, like principal component, factor
analysis, etc. But what exactly could I apply here? I really
appreciate your help.
