proc mixed for data with non-equal time point

Ken_oy — Thu, 20 May 2010 14:46:43 GMT

I have data as below:
5 categories: Delay0, 2, 4, 8 and 16.

There are 6 patients in each category.
In each category:
Patient1 to 4, were measured from day1 to day7;
Patient5 was measured from day1 to day6;
Patient6 was measured from day1 to day4;

I try to use SAS code as follow:
Proc mixed;
class delay day subject;
model value=delay day delay*day / s;
repeated day/ type=ar(1);
run;

When I run the code above there is no error or warning, but I am not so sure it is right.
Will Proc mix consider patient5 and patient6 as missing value? Thanks. Message was edited by: Ken_oy
