| pval.ICC2r.inter {irrICC} | R Documentation |
P-values of ICC(2,1) under Model 2 with subject-rater interaction, for 6 specific null values.
Description
This function computes 6 p-values for the Intraclass Correlation Coefficient (ICC) used as a measure of inter-rater reliability under the random factorial ANOVA model (Model 2) with subject-rater interaction. Each of the 6 p-values is associated with one of the null values 0,0.1,0.3,0.5,0.7,0.9.
Usage
pval.ICC2r.inter(dfra)
Arguments
dfra |
This is a data frame containing 3 columns or more. The first column contains subject numbers (there could be duplicates if a subject was assigned multiple ratings) and each of the remaining columns is associated with a particular rater and contains its numeric ratings. |
Value
This function returns a vector containing 6 p-values associated with the 6 null values 0,0.1,0.3,0.5,0.7,0.9.
