a matrix of observations with one subject per row and one
rater per column.
conf.level
confidence level of the interval. The default
is 0.95.
NAaction
a character string specifying what should happen
when the data contain NAs. 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.
Details
The calculation is based on one-way random-effects ANOVA and the details can be found in Baumgartner et al. (2015).
Value
Point estimate of the SDD and lower and upper bounds of the confidence
interval.
