weighing?

Hi everyone.

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
understand.

Your help is greatly appreciated. Many thanks.

Have a great day.

Re: weighing?

My dataset looks something similar to this:

id round log_exp timetask_1 ....... time_task_nth
1 1 112 3 ....... 1
1 2 90 0.5 ....... 5
.
.
.
nth 1 80 5 ....... 1
nth 2 100 0 ....... 3
nth 3 85 7 ....... 0

I'd really appreciate any helps.

Have a good day.
