Reliability fails with 0 cases as each case has missing values by design

Troubleshooting


Problem

I tried to use the SPSS Reliability procedure to calculate intraclass correlations (ICCs) for a set of four raters. Each rater actually rated only a subset of the cases so that each subject was rated by only two of the four raters. Many of the possible rater pairings were observed across the subjects. There is a variable in the data set for each rater, so each subject has missing values on two of the four variables that was input to the Reliability procedure. When I ran the Reliability procedure with these 4 variables, the procedure returned the error message: "There are too few cases (N = 0) for the analysis. This command is not executed." How can I get Reliability to run with the two valid ratings for each case, given that these ratings are spread over four variables?
