Calculate ICC(Two-way mixed effects, single rater, absolute aggrement)

tutu_ — Wed, 12 Jan 2022 23:25:54 GMT

I received a suggestion to calculate ICC for my research, so I'm referring to this paper for the concept of ICC (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4913118/)

Based on this paper, the ICC form will be Two-way mixed effects, single rater/measurement, absolute agreement. Is there any SAS programming example for this kind of ICC? Thanks in advance.

I am a bit confused - with a single rater, what are classes in your design that led to the suggestion that an ICC would be useful. I understand ICC's for multi-rater designs. So, to be able to give some advice, knowing the design for your data would be really helpful. Once the random effects are identified and output via ODS, calculation of the ICC is a proc transpose and a data step away.

icc = variance component for the classification variable of interest / sum of all variance components including residual
