Obtain confidence interval and point estimate of the intraclass correlation coefficient for one-way random anova model (ICC1).
agree.icc1(ratings, conf.level=0.95, method=c("sf"),
NAaction=c("fail", "omit"))
a matrix of observations with one subject per row and one rater per column.
confidence level of the interval. The default is 0.95.
a character string specifying the method used to obtain confidence interval of the ICC1. Now only the "sf" method is supported.
a character string specifying what should happen
when the data contain NA
s. It must be one of "fail"
and "omit" and may be abbreviated. The default is "fail" that causes
the function to print an error message and terminate if there are
any incomplete observations. If it is "omit", then the entire row(s)
containing incomplete observation(s) will be deleted.
Point estimate of the ICC1 and lower and upper bounds of the confidence interval.
The point estimate and confidence interval are based on a one-way random anova model as proposed in Shrout and Fleiss (1979).
