Hi all,
I have been asked to analyse a small dataset from a randomized controlled trial,
with 24 subjects (12 in each group, control and intervention). There are 3 sets
of continuous outcome measures (b1, b2, b3) taken at baseline, 7 weeks and 3
months, and 2 variables  which need to be controlled for  - level of impairment
impair (binary) and number of interventions numint (continuous integer).

If the data were normal I would have done something like this:

manova b1 b2 b3=group impair numint, continuous(numint)

and then do various manova tests.

Unfortunately the outcome data b1-3 are highly skewed, so I can't use manova.
What would be a good alternative?

Thanks.
