Hello dear SAS users,
I have a question about implementing correct ICC Intraclass correlation method on the below data. I am unable to understand if ICC1, ICC2 or ICC3 is suitable for the below data. I have looked up on the internet and though ICC2 would be suitable. But I am to double check and make sure my thinking is right. Please help me understand which id to select randomly GP_Id or Pat_Id or both. If so which is the suitable ICC method?
GP_Id | Pat_Id | No_of_Medications_prescribed |
1 | a | 1 |
1 | b | 2 |
1 | c | 4 |
1 | d | 1 |
1 | e | 2 |
2 | f | 7 |
2 | g | 2 |
2 | h | 1 |
2 | i | 7 |
3 | j | 8 |
3 | k | 9 |
3 | l | 4 |
3 | m | 6 |
3 | n | 4 |
Many thanks and best regards,
Chap
