Confidence Interval for A Single Intraclass Correlation (ICC)
|
||
|
|
-------------------------------------------------------------
|
||
|
|
|
||
|
|
.^iccconf <icc> <k> <reps>, level(#)^
|

^Description^
|
||
|
|
^-----------^
|
||
|
|
|
||
|
|
^iccconf^ is an immediate command that computes a confidence interval for a
|
||
|
|
single intraclass correlation (ICC). The procedure is based on Rosner's approach
|
||
|
|
using the F-test.
|
||
|
|
|
||
|
|
Three inputs are required:
|
||
|
|
|
||
|
|
^icc^ is the intraclass correlation. The input must be a value between 0 and 1
|
||
|
|
|
||
|
|
^k^ is the number of subjects
|
||
|
|
|
||
|
|
^reps^ is the number of repeated assessments or "within" pair
|
||
|
|
measurements.
|
||
|
|
|
||
|
|
^Option^
|
||
|
|
^------^
|
||
|
|
level(#) The level option allows the user to modify the confidence limit.
|
||
|
|
Use values between 0 and 1. The default is .95.
|
||
|
|
|
||
|
|
|
||
|
|
Example
|
||
|
|
--------
|
||
|
|
To find a 95% confidence interval for an ICC of .914, based on 5 observations
|
||
|
|
with 2 replcations each:
|
||
|
|
|
||
|
|
^.iccconf .914 5 2^
|
||
|
|
|
||
|
|
|
||
|
|
For a 90% confidence interval for the above example, type:
|
||
|
|
|
||
|
|
^.iccconf .914 5 2, level(.9)^
|
||
|
