msr2.fn {irrICC}

Mean of Squares for Raters (MSR) under ANOVA Model 2 with or without interaction.

Description

This function computes the MSR under the random factorial ANOVA model (MOdel 2). It can be used whether or not the subject-rater interaction is assumed. The MSR is used for calculating confidence intervals and p-values associated with the inter-rater and intra-rater reliability coefficients under model 2.

Usage

msr2.fn(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.
