Finding repeatability estimates of repeated measurements

jaelee22 — Fri, 13 Mar 2020 04:34:37 GMT

I have a date set on several repeated measures on different days.

Date Side measurements

1/2 x 21.2

1/2 x 22.3

1/2 y 20.0

1/6 x 21.0

1/6 y 19.7

1/8 x 20.1

1/8 y 22.2

1/8 y 24.7

like so. I am using proc glm, but I am not sure if I have done it correctly. I tried to do the calculation manually and get the pooled standard deviation in excel.

proc glm data= have; 
 class side; 
 model measurements = side date; 
run;

What do I have to use to get the within subject standard deviation, coefficient of variation, coefficient of repeatability and ICC of each side; not combined.

Any help is much appreciated.

Thank you
