st: wsanova syntax
Hi.
Can someone kindly lend assistance on the wsanova syntax for repeated
measures. I'm still a novice with STATA so hope anyone can assist.
There are 2 repeated variables: id and control. ID is person belonging
to group "control". Tthe same persons in year 1 (id) belonging to group
(control) were analyzed in time 2.
I want to compare the scores in time 1 and 2, between time (scores in
time 1 compared with scores in time 2) and control in time 1 and 2
(whether there was signicant difference in scores of "control 1" at time
1 to scores at time 2, and within "control" in time 1 and 2 (whether
there was significant difference between scores of "control 1 and 2" in
time 1 compared to time 2).
time id control score
----------------------------------
1 1 1 5
1 2 1 6
1 3 1 5
1 1 2 3
1 2 2 4
2 1 1 7
2 2 1 8
2 3 1 5
2 1 2 2
2 2 2 10
I used: wsanova SCORE CONTROL, id(ID) between(TIME). Is this correct?
Thanks in advance.
