Namely, I have overlooked two important aspects of the study; which,

The first aspect are the

My own suggestion (mangled by a bad emailer) was to use vector time
I don't know enough about time series really to provide much advice.
However, I have seen methods by which a slope was calculated across time for
each subject with the first measurement as the incercept (within subjects).
Subsequently, the individual slope was regressed on other factors. Thus,

time series for _each_ of 120 subjects ? There has been a controlled
study where patients in three independent groups were asked to keep

I don't think so. I can think of many examples in which statistical
