Subject: weighted regression?
Content-Type: text/plain; charset=ISO-8859-1
I maybe asking a very easy question here but I have a dataset with
vary numbers of repeated A measurements for each individuals. During
each measuring round, each individuals would do more than one task for
a certain time. What would be the most appropriate way to analyze it
if my interest is to find out what task contributes to higher A
exposure and at the same time taking into account the correlation of
the repeated A measurements? I've been told to use weights but i don't
Your help is greatly appreciated. Many thanks.
Have a great day.
