Hello各位高手:
想請教版上大人關於estimate的問題
不是很確定estimate要怎麼寫 看了很多網路上的資料還是很茫然
特別是下面的3 way interaction的部分
[color=#FF0000:1b5zenr8]Exposure*Group*Time ??????? 要怎麼寫?[/color:1b5zenr8]
Exposure coding= 1 or 0
Group coding= 2 5 9
Time=continuous variable
[code:1b5zenr8]
Proc Mixed data=test;
class id group;
model sp_norm = Exposure Group Time
Exposure*time Group*time
Exposure*Group*Time /solution ddfm=kr cl alpha=0.05;
random intercept time/ type=un subject=id;
Estimate "GROUP:9" time 1 group*time 0 0 1 Exposure*Group*Time ???????;
