Hi,
I have a dataset with 23 raters (ie vars ID1 - ID23) who rated 7 statements (var 'statement') on the scale from 1 (strongly disagree) to 5 (strongly agree). The same 7 statements were assessed at two other time points (ie Round 2 and Round 3 of the Delphi survey).

First, I ran this command (see below) to calculate Gwet's AC1 for all 7 statements separately in Round 1, 2, and 3. As expected, the degree of agreement is increasing in every following round AND the output contains 95% CI:
kappaetc ID1 - ID23

However, I'd also like to look at Gwet's AC for each of the statements separately, but while I do get Gwet's AC1 there are dots/empty spaces instead of CIs in these outputs:
kappaetc ID1 - ID23 if statement==1

I'm pretty sure it has to do with the fact that when trying to calculate Gwet's AC1 for each statement I have only 1 'subject' that is being rated by 23 raters, but I see papers that are designed in the same way and they do provide CIs for each item/statement. Any insight? Any help would be very much appreciated.
Kindly,
Julia
