Hi Alina,
your approach sounds problematic - you can always get a smaller RSS if
you add terms to your model, so your approach will always go for larger

Al,
Is there any "ID" index for the pairs? For example, if the first pair can be
labeled "a", and second pair labeled "b" etc., then you can add an index
column or you may already have such a column in your list. Then run
aggregate(your.data.column, by=index.column, FUN=mean). Or you can just add
Dear All,
this is my first post to the R-help, so please don't be too strict.
My problem concerns a QQ-Plot:
I want to show how well empirical samples match with a theoretical
distribution. The theoretical distribution has got several parameters, but I
made it to fit via ML.
Anyway
Hello,
I'm trying to create a for loop for a data set, I have a list of results in
this data set and I want to take the 1st two add them together and divide by
the mean of the 1st to, then do the same for the 3rd and 4th values in the list
and so on and each time return a value for the calcul
Oh, and to answer your question more directly, the randomization test
permits testing hypotheses using any metric, so scale & shape are
definitely testable.
Typically one is interested in means, so on each iteration of the test
loop one computes the group/condition means. However, it's simple to
